In this paper, we propose a design method for low-power self-timed combinational circuits and latches based on the 1-out-of-4 encoding method. We propose a 1-out-of-4 latch circuit using standard cell libraries in order to establish a semi-custom low-power self-timed design style. The energy consumption of the proposed circuits is about 18% average smaller than that of conventional dual-rail encoded circuits.
