Abstract
A circuit and method for providing a regulated output voltage is described. The circuit includes a capacitor array, a comparator and an output control module. The capacitor array receives an input voltage, first and second control signals, and generates a regulated output voltage in response. The comparator compares the regulated output voltage and a reference voltage, and generates a comparator signal in response. The output control module receives the comparator signal and the first control signal. In response, the output control module provides the second control signal to the capacitor array.
