Patent Number: 8,791,726

Title: Controlled resonant power transfer

Abstract: Recycling energy in a clock distribution network is provided. A circuit includes a clock driver associated with a clock signal and having an output connected to a first load capacitance. The circuit also includes a second load capacitance connected in parallel with the first load capacitance. The circuit further includes a power transfer circuit including an inductor and a transmission gate connected in series between the first load capacitance and the second load capacitance. The power transfer circuit controls a flow of energy between the first load capacitance and the second load capacitance based on the clock signal.
