Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...
A microwatt charge-pump boost converter from two ultra low power op amps. Boosting the output voltage of common alkaline button-cells to at least 1.8V needed by microcontrollers provides an “always on ...
Charge pumps represent an established topology for dc-dc converters that generate low-power inverted and doubled replicas of the input voltage. Typical output currents are as high as 150mA. Such ...
