US Patent 7750715 Charge-sharing method and device for clock signal generation

A clock generation circuit has two output ends to provide a first clock signal and a second clock signal, in response to first and second input signals, respectively. A charge storage component is used to transfer some charge from the first output end to the charge storage component when the first clock signal is high for a period of time, and to transfer the charge from the charge storage component to the second output end when the second clock signal is low. At a different period of time in the clock cycle, the charge storage component is used to transfer some charge from the second output end to the charge storage component when the second clock signal is high for a period of time, and to transfer the charge from the charge storage component to the first output end when the first clock signal is low.
