Alan Walsh, Analog Devices Part 1 If the ADC throughput is reduced to 10 kSPS then the current consumption of the ADC scales linearly down to 15 uA (factor of ~100) and correspondingly, the switching frequency ripple of the ADP5300 scales to 46.5 ...
Ron Michallik, Texas Instruments Electronic Design This Idea for Design rearranges the schematic and physical layout of an isolated dc-dc converter using a shunt regulator to overcome susceptibility to ESD and electrical overstress. Did you know ...
Christopher Dean, Texas Instruments Electronic Design By adding a digital potentiometer and ratiometric division to a voltage-reference IC's feedback loop, you can set the reference's output voltage using a digital code. Adjustable voltage ...
There are a variety of reasons why a system designer may want to consider paralleling of DC power supplies. Some of these are related to the bill of materials and logistics issues, others are focused on satisfying system current, performance or ...
Battery University Discover what causes Li-ion to age and what the battery user can do to prolong its life. Battery research is focusing on lithium chemistries so much that one could imagine that the battery future lies solely in lithium. There are ...
Any hobbyist can charge a battery quickly, but can you do it without an explosion, excessive heating or major degradation in battery cycle life? Well many companies have managed fast charging techniques that typically use specialized algorithms. ...
By Qui Luu, Analog Devices Analog Dialogue Part 1 Analysis The plots provide invaluable data on the supply sensitivities at each power pin. VPOS_PLL has the worst power-supply rejection and is therefore the most sensitive power node. This power pin ...
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 ...
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 ...
