ABSTRACT:
The present invention provides an energy recovering driver that includes a pull-up control, a pull-down control and a transmission gate. The pull up control is responsive to a pull-up control signal and a clock signal to turn the transmission gate ON and OFF and predetermined positions of the clock signal. The pull-down control is responsive to a pull-down control signal and the clock signal to turn the transmission gate ON and OFF at other predetermined locations of the clock signal. The transmission gate transmits the clock signal when at an ON condition and does not transmit the clock signal when in an OFF condition.
