Abstract:
1. An energy recovery driver comprising: a pull-up control that receives a pull-up control signal and a sinusoidal clock signal. a pull-down control that receives a pull-down control signal and the sinusoidal clock signal; a transmission gate that transmits the sinusoidal clock signal when in an ON condition and that does not transmit the sinusoidal clock signal when in an OFF condition; wherein the pull-up control is responsive to the pull-up control signal and the clock signal to turn the transmission gate ON at a first pull-up position on the clock signal and to turn OFF the transmission gate at a second pull-up position on the clock signal; wherein the pull-down control is responsive to the pull-down control signal and the clock signal to turn ON the transmission gate at a first pull down position on the clock signal and to turn OFF the transmission gate at a second pull-down position on the clock signal.
