Abstract

In this paper, we present a new sense amplifier based flip-flop that exploits input data activity, to achieve reduced power consumption. The internal nodes of the proposed flip-flop are charged/discharged only when the input data changes state. Simulations show that the power consumption of proposed flip-flop is reduced by 20% to 70% compared to standard sense-amplifier flip-flop. An FIR-filter based on the proposed flip-flop, implemented in 45nm ST process, shows more than 42% improvement in power consumption (with 5% delay penalty) compared standard sense-amplifier flip-flops.
