VOLTAGE GENERATOR USING PUMP CIRCUIT

摘要

disclosed is a voltage generator using a multi-stage pump circuit including a plurality of pump circuits and a plurality of ring oscillators. The plurality of pump circuits are parallel connected one another. The plurality of ring oscillators have different periods one another. The voltage generator is pumping in response to the signal output from the plurality of ring oscillators. Thus, latch-up and noise of power line can be reduced.
