Charge pump circuit for use in high voltage generating circuit
A charge pump circuit includes a plurality of serially connected pump stages. Each pump stage includes current paths connected between a gate terminal of a charge transfer transistor and a drain terminal thereof. One of the charge transfer paths allows charges to be transferred from the drain terminal to the gate terminal while the other path allows charges to be transferred from the gate terminal to the drain terminal. The charge pump circuit can generate a high target voltage using a very low power supply voltage (e.g., 2V or lower).
