Abstract :
Resonant clocking is a form of adiabatic clocking that retains much of the energy present in clock switching and recycles it into the following clock cycle. In this paper we present the first automated methodology using LC-assisted local clock buffers (LCLCB) for generating local resonant clocks. This uses a single-buffer single-inductor sector topology applied to non-uniform trees as found in most ASIC designs. We show that this form of adiabatic clocking can achieve power savings as much as 75% over traditional buffered clock networks.
