ABSTRACT:
The voltage generator circuit according to the invention has a first negative potential generator circuit to generate a first clock signal going negative and oscillating at negative voltage in response to a first clock signal oscillating at positive voltage, a second negative potential generator circuit to generate, in response to a second clock signal oscillating at positive voltage, a second clock signal going negative and oscillating at negative voltage and having an amplitude greater than the amplitude voltage of the first clock signal going negative, and an output circuit to deliver the lowest voltage of the first clock signal in response to the second clock signal going negative.
