摘要

A circuit technique is presented for reducing the subthreshold leakage energy consumption of domino logic circuits. Sleep switch transistors are proposed to place an idle dual threshold voltage domino logic circuit into a low leakage state. The circuit technique enhances the effectiveness of a dual threshold voltage CMOS technology to reduce the subthreshold leakage current by strongly turning off all of the high threshold voltage transistors. The sleep switch circuit technique significantly reduces the subthreshold leakage energy as compared to both standard low-threshold voltage and dual threshold voltage domino logic circuits. A domino adder enters and leaves a low leakage sleep mode within a single clock cycle. The energy overhead of the circuit technique is low, justifying the activation of the proposed sleep scheme by providing a net savings in total power consumption during short idle periods.
