The proliferation of cellular phones, tablets and other Internet-connected devices (the Internet of Things) has drastically increased the amount of wireless communications traffic throughout the world....
View ArticleDesigning an IoT modular light – part 2
In the first installment of this two-part series, I talked about an illuminating idea I had for a project I could use in my newborn baby’s room: an Internet of Things (IoT) modular light. I’ve done the...
View ArticleFemtoFET MOSFETs: small as sand but it’s all about that pitch
What contains more silicon: a grain of sand or TI’s latest FemtoFET product? As I sit in my beach chair watching the waves of the Atlantic roll onto the Jersey shore, my mind drifts over this...
View ArticlePowering the Altera Arria 10 GX
Field programmable gate arrays (FPGAs) are increasingly complex system on chips (SoCs) that include not just programmable logic gates and random access memory (RAM) but also analog-to-digital...
View ArticleEnabling 48V-to-POL single-stage conversion with GaN
Enterprise server, switch, base station and storage hardware designers are always looking to increase power density and efficiency on their motherboards. With the addition of more components on the...
View ArticleScope plot surgery – my boost converter has an off-ramp!
As an applications engineer, I often get inquiries about voltage and current flows in switching regulators. And I often realize that the basic theory I learned in college doesn’t always tell the whole...
View ArticlePowering Intel’s Xeon D SoC in servers, storage and switches
Intel’s Xeon D chip, developed under the Broadwell-DE code name, is the first Xeon central processing unit (CPU) to bear the system-on-chip (SoC) title by including two physical chips in one package....
View ArticleCan an LDO produce better-quality images in small-sized camera applications?
Digital imaging electronics are becoming more portable and integrated into high-quality solutions. The cohesiveness of high-performance and small-sizes in camera applications is often influenced by the...
View ArticleUSB Power Delivery 2.0 vs 3.0
When I first heard about the movie “Batman v Superman: Dawn of Justice,” I was confused because they are both the “good guys.” Since USB has released a limited distribution of a new USB Power Delivery...
View ArticleWhy is the cloud isolated?
In this day and age of bits and bytes, the demand for information transfer and retrieval is ubiquitous. Whether in line at the grocery store or waiting for a train, we use our smartphones to check our...
View ArticleDecrease power consumption with an LDO
A low-dropout regulator (LDO) can function as a DC linear voltage regulator at an output voltage very close to the supply voltage, which is an important factor in decreasing power dissipation across...
View ArticlePower Tips: Multiply your output voltage
Voltage multipliers provide a simple method to create high-voltage outputs at low currents. They are useful in applications such as printers, sensors and charged-particle systems that require anywhere...
View ArticleHow you measure your ripple can make you or break you
Testing switching power supplies includes many different tests, one of them being the output-voltage peak-to-peak ripple. Output-voltage ripple is the alternating current (AC) component of the direct...
