Driver circuits that save switching power by 25 % or more using LC resonance energy recovery are shown for use in clock and data networks. Resonant and other energy savings circuits are shown from global to local leaf cell clocking. A 10× operating frequency range with power reductions allows dynamic voltage and frequency scaling for power management. The resonance used only for the brief transition...
An energy efficient and area saving local clocking scheme using new resonant techniques is illustrated with a bank of 1024 flip-flops. Energy recovering pulsed resonant (PR) clocking is designed to drive explicit-pulsed negative setup time latches. A pre-driver that generates tracking pulses at each transition of clock for dual edge (DET) operation is robust across PVT. While both the pre-driver and...
An energy recovering scheme for 40% savings in clocking power with 40% driver active area reduction is demonstrated. A new resonant driver that generates tracking pulses at each transition of clock for dual edge operation across scaled frequencies is proposed. Pulsed resonant (PR) clocking is designed to drive explicit-pulsed negative setup time latches. Simulations using 45nm IBM/PTM device and interconnect...
