摘要: An improved substrate bias generator for MOS integrated circuits is described. The includes circuitry generating two trains of periodic pulses which are approximately phase opposite, one the pulse being slightly delayed as compared to other train. applied a pumping circuit generates target voltage and initially transfers positive charge into substrate, thereafter out substrate. transferred greater than when absolute value potential on less voltage. Otherwise, net In this manner, driven towards
