By Qui Luu, Analog Devices Analog Dialogue As more building blocks are added to a radio-frequency integrated circuit (RFIC), more sources of noise coupling arise, making power management increasingly important. This article describes how ...

Chris Glaser Electronic Design A new power-conversion method, called automatic efficiency enhancement (AEE), provides higher efficiency with lower output voltages in power supplies for systems such as tablets, servers, and solid-state drives. A ...

By Stephen Evanczuk Digi-Key In any power-distribution system, non-resistive loads cause current and voltage to shift out of phase, resulting in energy lost as reactive power. While current and voltage will remain in phase in the case of a purely ...

There has been many developments of Arduino based motor controller boards and shields. They work great with most low power motors but when you need to do more serious motor driven project, then you find that most of those shields aren’t ...

NTU Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes. The new generation batteries also have a long lifespan of over 20 years, more than 10 ...

Bruce Dorminey, Contributing Editor Renewable Energy World Magazine Both the developing and the developed world have reasons to employ battery technology. Here’s why. Battery technology has come a long way since the days when your granddad ...

Jess Espiritu, Analog Devices Analog Dialogue Introduction Power-supply sequencing is required for microcontrollers, FPGAs, DSPs, ADCs, and other devices that operate from multiple voltage rails. These applications typically require that the core ...

Rich Nowakowski and Robert Taylor, Texas Instruments Analog Applications Journal Linear regulators have been around for many years. Some designers still use linear regulators that are over 20 years old for new and old projects. Others have made ...

Kris Lokere, Linear Technology EDN Introduction The “Internet of Things” refers to a growing trend to connect not only people and computers, but all sorts of “things” to the Internet. In applications such as industrial ...

Michael Kugelman Power Electronics Two new patented circuits control AC power to resistive and reactive loads with minimal EMI. They are applicable to single and multiple AC phases and varying AC frequencies. Switching AC power on and off has been ...
