Abstract

A charge pump circuit for generating a negative voltage has a switched capacitor voltage inverter circuit arranged to receive at least one clock signal and generate a negative voltage therefrom; a regulation control loop providing a feedback path from the output of the switched capacitor voltage inverter circuit to a supply input of the switched capacitor voltage inverter circuit, wherein the regulation control loop has a filter arranged to filter the generated negative voltage; and an output arranged to output the filtered generated negative voltage.
