Double-swing clock generator and charge pump

摘要

A double-swing clock generator includes a first double-swing clock generation circuit and a second double-swing clock generation circuit. The first double-swing clock generation circuit is used for receiving a first voltage, a second voltage, a first clock, an inverse first clock, and a third voltage, and outputting a first double-swing clock. The second double-swing clock generation circuit is used for receiving a fourth voltage, the second voltage, the first clock, the inverse first clock, and the third voltage, and outputting a second double-swing clock.
