Abstract

A charge pump circuit arrangement comprises a multitude of capacitors (110, 111, 112, 113) of a first and a second group controlled by non-overlapping clock pulses (CLK1, CLK2). The capacitors are partly realized in a semiconductor substrate including a deep well doping region and a high voltage doping region surrounded by the deep well doping region. Switches (324, 325) are connected to a pair of capacitors to control the deep well doping regions with signals (CTRL1, CTRL2) in phase with the corresponding clock signal (CLK1, CLK2).
