发明名称 HVNMOS/HVPMOS switched capacitor charge pump having ideal charge transfer
摘要 An integrated circuit for a charge pump with a charge stage and a pump stage and a single High-Voltage PMOS (HVPMOS) transistor as the main switch for each stage and two times two minimum HVPMOS transistors in series as a bulk switch with fixed bulk connections, where the minimum HVPMOS transistors are smaller sized transistors than the transistors of the main switch. The bulk of the main switch is switched synchronously to the voltage node of the HVPMOS transistor of the main switch to force the bulk voltage (VB) to be equal or larger than either the source voltage (VS) or the drain voltage (VD). Two non-overlapping clock signals are used to trigger the HVPMOS transistors of the charge and pump stage.
