More Information
Summary:A kick back compensated charge pump circuit with kicker capacitor is disclosed. The charge pump circuit comprises a pump up circuit that comprises a first PMOS transistor and a second PMOS transistor in a cascode configuration and coupled to a first kicker capacitor. The charge pump circuit also comprises a pump down circuit that comprises a first NMOS transistor and a second NMOS transistor in a cascode configuration and coupled to a second kicker capacitor. The kicker capacitors increase the speed of the charge pump circuit by charging and discharging a gate to source capacitance (CGS) of the pump up circuit and of the pump down circuit of the charge pump circuit.
