ABSTRACT:
A charge pump for increasing the amplitude of a voltage supply signal is disclosed. The charge pump includes an auxiliary pump, a buffer stage, and a main pump. The auxiliary pump generates several intermediate voltage signals in response to a pair of complementary clock signals. Each intermediate voltage signal has a different amplitude which is greater than the amplitude of the voltage supply signal. The buffer stage increases the amplitudes of the pair of complementary clock signals in response to the several intermediate voltage signals generated by the auxiliary pump. The main pump increases the amplitude of the voltage supply signal in response to the pair of increased amplitude complementary clock signals generated by the buffer stage.
