In the first half of switching cycle, the circuit capacitor C1 is charged to the input voltage and in the second half of the switching cycle the voltage is then inverted and applied to a capacitor C2 and load. This leads to the input voltage to be negative of the output voltage and defined as the Duty cycle which is the ratio of charging time of a capacitor C1 to the entire switch cycle time. This is almost always because 50% is the yield of the optimal charge transfer efficiency. The capacitor C1 has to supply only a small amount of charge during the time period of transient conditions startup to the output capacitor on each switch cycle and on steady state conditions.
The capacitor C1 is also known as a charge pump capacitor with the charge transferred depending upon the current load and the frequency of the switches. The output capacitor C2 must supply the current load during the time the input voltage is charging the charge pump capacitor. This will cause a droop in the output voltage caused by the load current flowing out of the C2 which also happens to correspond the output voltage ripple of a component. The high frequency of the switching allows smaller capacitors to droop and switching the frequency will require a different size of external capacitor required though the frequencies will be limited to a few hundred Khz. While switched capacitors inverters are low cost in nature, the efficiency and compactness achieved are greater than 90% while the maximum output current of typical switched capacitor inverters are 150mA maximum.
Single power supply system only require a few high performance parts with negative voltage whereas relatively low current negative voltage is required in addition to positive primary voltage. Voltage doublers are primary used in low current applications and adding regulation to the switched capacitor voltage converters increases the effectiveness of its application. Finally LDO which is low dropout linear regulator is the most straightforward and provides the regulated output while also reducing the ripple of the switched capacitor converter. This approach reduces the available output voltage by the dropout voltage of the LDO but will also add to the complexity of the approach. Another highly non-linear approach requires long time constants to vary the duty cycle of the switch control signal in order to maintain good regulation control.

Intel announced a new range of products with more innovative capabilities and better performance than any of their previous processors. The event held in April of this year featured numerous Intel architecture-based products including tablets, laptops, 2-in-1 devices, and PC computing sticks.
Thaine Creitz, Director of Consumer Technical Marketing for Intel, addressed the importance of using the latest technology for better execution and experience. This was demonstrated with a complete comparison of the new Intel sixth-generation processors to those which were the leading processors 5 years prior. The new intel architecture eased through performance tests that measured competency to run high-end 4k videos, editing, multi-tasking, and gaming.
Some of the highlights at the event included discussion of forthcoming devices, such as the Intel RealSense Camera – which features 360-degree broadcasting and better memory capabilities with new Optane technology. RealSense equips gamers with the technology to have the best experience yet, as it even enables users to scan real-life objects and create 3D versions that can also be printed in 3D. Intel HD and Iris graphics were two other new products discussed that grant the capability to execute tasks such as editing photos and videos with ease. Having these built right into the processors—whether 2-in1, portable all-in-1, or desktop computers—allows for the development of lighter and portable models.
Creitz believes this innovative technology is just the introduction to an entire new realm of computing technologies possibilities.

Apple, the American multinational technology company, has recently made some plans for new hardware. According to a new report, the company might be launching a new hardware soon, and chances are that it will be expensive. According to an Apple tracking website, 9to5Mac, it appears as though in anticipation for a refresh to the new hardware, Apple has been covertly depleting stock on their Thunderbolt Display, which is priced at $999 each. The site has suggested that Apple will be replacing this Thunderbolt Display with a 5K resolution version. This upgraded display will also be equipped with an integrated graphics chip which will enable the display to offer high-quality visuals.
“While Apple did not immediately respond to a request for comment on the report, Fortune was able to verify that many Apple retail stores are not carrying the 27-inch Thunderbolt Display right now,”
said Don Reisinger from Fortune.
“However, the company’s online store is still selling the device, and customers could get it as soon as tomorrow. Most other online retailers are selling used or refurbished models of the device.”
This trend in Apple’s behavior seems to follow a pattern that Apple has utilized in the past. Typically, Apple allows for the supply of its products to gradually deplete while the company works on developing a replacement product. As soon as this new product is ready to launch, units of the preceding model are eventually replaced with the newer, superseding model. Many seem to believe that it is possible that Apple is doing the same with its display.
“Launching a new display seems to make some sense for Apple. The Thunderbolt Display hasn’t received a meaningful upgrade in quite some time, and although it offers an overall solid visual experience, including a 2,560-by-1,440 resolution and a 1,000:1 contrast ratio, there are cheaper alternatives available that boast better specs,”Reisinger added.
“Apple, in other words, might need to catch up.”

Airbus is introducing a brand new corporate-jet version of their popular A350 XWB airliner outfitted with their Easyfit provisions for cabins. This new aircraft will further expand Airbus’ corporate jet family by offering an aircraft that can deliver even more comfort, capacity and capabilities. Christened the ACJ350 XWB, the aircraft features 270 m2/2,910 ft2 of cabin space in the -900 version with the ultra-long variant able to fly up to 25 passengers at 10,800 nm/20,000 km or 22 hours thus making it the most modern and capable corporate jet offered on the market. XWB stands for Extra Wide-body and the ACJ350 delivers Extra of everything. Extra comfort coupled with innovative technology, efficiency and the added bonus of being extra easy to outfit.
The issue with wide-bodied aircraft lies in the fact that creating cabins that meet the demanding certification rules are challenging and especially so when they are installed with fuselage made of carbon fiber. To remedy this Airbus has decided to pre-equip the carbonfibre fuselage for the ACJ350 with hundreds of attachment points to greatly simplify the work of cabin-outfitters all the while working hand in hand extensively with cabin outfitters to ensure a smooth and seamless completion of the cabins. John Leahy believes that one of Airbus’ greatest strengths is the ability to offer modern and efficient aircraft that are able to cater to and adapt to the ever-growing and ever-changing needs of its customers.
Easyfit is just another example in a long list of options that Airbus has offered to the public in order to acclimatize to the demands. Beyond the standard creature comforts, the ACJ350 also offers enhanced protection of fly-by-wire controls, extensive use of weight and maintenance-saving materials and time and cost-saving centralized maintenance. Additionally, the ACJ350 XWB delivers a standard on-board navigation system (OANS) similar to a GPS along with runway overrun prevention system (ROPS) which is a tool to aid pilots in preventing runway excursions that often occur in challenging weather. Airbus has already begun delivering A350-900 back in December of 2014 and with the A350-1000 currently in development with an expected airline service date of 2017, Airbus has already won over 800 orders from more than 40 different customers worldwide.

BBC News has recently reported that the United States nuclear weapons force still uses 8-inch floppy disks as well as a 1970s-era computer system. This information was revealed through a government report. According to the Government Accountability Office, the Pentagon, along with several other departments, are in desperate need of having their “legacy systems” urgently replaced. The government report suggested that taxpayers spend around $61 billion per year just to maintain these ageing technologies. This amount of $61 billion a year is said to be roughly three times more than the cost of investments for modern information technology systems. The government report revealed that the United States Department of Defense systems which coordinated intercontinental nuclear bombers, ballistic missiles, as well as tanker support aircraft
"Runs on an IBM Series-1 Computer - a 1970s computing system - and uses eight-inch floppy disks."
"This system remains in use because, in short, it still works,"
said Lt Col Valerie Henderson, a Pentagon spokeswoman, to the AFP news agency.
"However, to address obsolescence concerns, the floppy drives are scheduled to be replaced with secure digital devices by the end of 2017."
"Modernization across the entire Nuclear Command, Control, and Communications enterprise remains ongoing,"
added Lt Col Valerie Henderson.
The government report stated that the Pentagon has scheduled to have their systems fully replaced by the end of 2020. According to the government report, the United States treasury is also in need of a systems upgrade, which is currently using
"Assembly language code - a computer language initially used in the 1950s and typically tied to the hardware for which it was developed."

Alud Davie released a web log post on May 18th 2016 on Corporate Jet Investor talking about the Gulfstream mode G650ER and how it has set a new record on its course from Sydney to Los Angeles.
The Gulfstream G650 and G650ER have over 50 world records to its name for various types of activities.
To get an idea of the time it took the Gulfstream G650ER to travel from Sydney to Los Angeles, here is what Davies wrote.
“The aircraft departed Sydney Airport during the morning of March 11, and arrived at Los Angeles International Airport 12 hours and 40 minutes later at 01:15 March 12.”
The average cruise speed for this flight is around Mach 0.86. This flight was over 12,000 km long.
The documentation for this record has been sent to the Fédération Aéronautique Internationale in Switzerland. Although the documentation has been sent for review, the US National Aeronautic Association has already approved of the record.
Here’s what Scott Neal, senior vice president, Worldwide Sales and Marketing, Gulfstream has to say.
“This latest speed record is another demonstration of the G650ER’s superior capabilities. The unmatched range and speed of the G650ER enables operators to reach more destinations nonstop quickly and efficiently. No other business aircraft can connect Sydney to Los Angeles faster than the G650ER.”
Gulfstream is a company that was founded in 1958. It’s headquarters is in Savannah, GA. Allen Paulson is the founder of Gulfstream aerospace. Gulfstream’s parent organization is General Dynamics. Since starting, Gulfstream has produced well over 2000 aircrafts. The company has over 13000 employees.

Many companies in the semiconductor sector are struggling to find finance chiefs who are capable of leading transformational changes in the complex industry. These potential Chief Financial Officers are expected to thin margins while simultaneously counteracting plateauing sales as well as downsizing a workforce worldwide. Many companies in Silicon Valley are searching for someone with experience in reducing costs, minimizing head count, and pivoting product portfolios following years of fast-paced growth.
Intel Corporation, one of the world’s highest valued and largest semiconductor chip makers, is currently looking for a new CFO to fill the CFO vacancy which was left by Stacy Smith, who was promoted to an operational role last month. Other chip makers, such as Qorvo Inc. and Marvell Technology Group Ltd., are also on the search for a new Chief Financial Officers.
“The CFO role at Intel is a challenging job…Intel’s next CFO, whether from inside or outside the company, will inherit a world-class team and a company that is growing and financially strong,”
Mr. Smith in an emailed statement.
Intel’s new Chief Financial Officer will be expected to decrease Intel’s dependence on personal computing, reduce heat count by 11 percent (or 12,000), as well as deliver yearly savings of $1.4 billion by the middle of 2017. The new Chief Financial Officer will also be responsible for furthering Intel’s cloud-computing efforts, expanding Intel’s memory chip business, and broadening chip usage in devices connected to the Internet.
“It’s difficult to find people qualified to do that role,”
said an analyst from the global investment banking and diversified financial services Macquarie Group, Deepon Nag.
“The semiconductor industry is a very complex industry…and it requires someone who is familiar with all these parts.”
“While Intel may welcome an external hire, the next CFO is likely to come from within the semiconductor sector,"
suggested Tatyana Shumsky from the Wall Street Journal.
“Boards and executives tend to want someone who understands the risks associated with the industry, recruiters say… industry CFOs in the throes of reallocating capital from flagging business lines and evaluating acquisition opportunities face a long slog. It can take years for billion-dollar investments in new technologies to reach the market.”

On March 25 2016, Nikkei Asian Review released an article that was about how manufacturers of electronic parts are still reeling from Apple’s iPhone production cost. It seems as if the iPhone 6s and iPhone 6s plus has had a heavy emphasis on shipments of electronics parts from Japan. With this happening, it does not seem that the company has any signs of recovery.
Here’s what one of the executives at a major manufacturer has said recently.
"Apple notified us in the second half of November that it would reduce production."
Although being a supplier of a huge US giant in the mobile industry means that the supplier will benefit greatly, such suppliers will also feel affects if the huge US giant in the mobile industry is not doing well.
In the first time in three years, Japanese manufacturers are experiencing a decline in sales. Data shows that in December, numbers have dropped by 5.6%. This data was provided by the Japan Electronics and Information Technology Industries Association show.
Companies such as Alps Electric has readjusted their company’s forecast from almost 50 billion yen to 40 billion yen in January. Not only has iPhone sales underperformed, the Japan yen is not as strong as it used to be compared to the US dollar.
It seems that even Chinese and South Korean smartphone makers expect phone sales to be more stagnant.
With all this coming into play, it seems as if many manufacturers are becoming more cautious of the future and deciding to put a lower dependence on phone sales.

For the only the second time in the history of Semiconductors, the industry is expected to experience two consecutive years of decline in revenues. According to James Hines who is a research director at Gartner, the industry is expected to decline at a 0.6 percent clip in 2016 and the market is desperate for the next in demand driver to emerge and consequently become the tide that lifts all boats so to speak. The worldwide semiconductor revenue figures for 2016 is forecasted to generate a total of $333 billion which is a slight decrease of 0.6 percent from 2015.
This follows on the heel of an even more dramatic 2.3 percent drop in 2015 from 2014 due to trend of weakened demand for key electronic equipment. The lower demands is exacerbated by elevated inventory levels and the continuing impact of the dollar fluctuation in key regions around the world. The sharp drop in demand for semiconductors in 2016 can be traced directly to the lowered estimations for production in regards to PCs, smartphones and ultramobiles. With no ground-breaking or in-demand driver set to emerge in the near future, relief for the semiconductor market to offset the reduction in demands is nowhere in sight. The Internet of Things (IoT) and wearable electronics could resuscitate a fading market but these devices are still in the infancy stages of dearly development.
They will then have to pass through a lengthy testing phase to get rid of all the bugs and design flaws, after which a lengthy quality period is follows and finally culminating in a costly marketing phase before the semiconductor industry start seeing any type of significant impact on the overall revenue growth. The Internet of Things or IoT can be classified as a network of physical objects whether they be devices, vehicles, buildings or even accessories that are embedded with electronics, sensors/software with network connectivity. They are becoming increasingly complex and with the features and applications they provide makes them high-value commodities. The Term was first coined by Kevin Ashton while working at Auto-ID Labs back in 1999 and initially referred to a global network of objects connected by radio-frequency identification or RFID.
