When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources ...

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 ...

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 ...

What is a charge pump? A charge pump provides dc-dc voltage conversion using a switch network to charge and discharge two or more capacitors. The basic charge pump switch network toggles between ...
