A voltage regulator control circuit.

摘要

A voltage regulator control circuit including a capacitor network and a switching network which provides controllable connections among the capacitors of the capacitor network. The switching network is operable to alter the controllable connections in a repeating sequence to provide an output control signal that is a measure of the difference between an input reference voltage applied to the voltage regulator control circuit and a voltage controlled by the voltage regulator control circuit. The voltage regulator control circuit relies on differential voltage translation and filtering using switched capacitor networks and includes a reference input port for receiving an input reference voltage, a controlled-voltage input port for receiving an output voltage from a voltage regulator to be controlled, a capacitor network, a control signal generator and a switching network for providing controllable connections among capacitors of the capacitor network, the reference input port, the controlled-voltage input port and the control signal generator. <IMAGE>
