Patent ID: 8742836

Claim:
A double-swing clock generator, comprising: a first double-swing clock generation circuit 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, wherein a swing of the first double-swing clock is two times to a swing of the first clock, the first double-swing clock generation circuit comprising: a first precharge unit for receiving the first voltage and the second voltage; a first capacitor coupled to the first precharge unit for receiving the first clock; a first charge transfer unit coupled to the first precharge unit for receiving the inverse first clock and outputting the first double-swing clock; and a second precharge unit coupled to the first charge transfer unit for receiving the third voltage; and a second double-swing clock generation circuit for receiving a fourth voltage, the second voltage, the inverse first clock, the first clock, and the third voltage, and outputting a second double-swing clock, wherein a swing of the second double-swing clock is two times to the swing of the first clock, the second double-swing clock generation circuit comprising: a third precharge unit for receiving the fourth voltage and the second voltage; a second capacitor coupled to the third precharge unit for receiving the inverse first clock; a second charge transfer unit coupled to the third precharge unit for receiving the first clock and outputting the second double-swing clock; and a fourth precharge unit coupled to the second charge transfer unit for receiving the third voltage.
