ABSTRACT:
A bandgap reference circuit can use various output stages to implement a controlled feedback method of sensing and supplying the needed load current through a sensing network. A small amount of circuitry can be added to a class AB output stage to decouple the bandgap reference feedback from a capacitive load and simultaneously sense load current needs and boost current as needed while minimizing voltage droop. Such circuits can be implemented using relatively compact designs while still reducing droop, and thus allowing the use of a large external capacitor to reduce noise and maintain good power supply rejection.
