Abstract::Pulsed-latches emerge as an ideal sequencing element for low power digital circuit design, serving as an alternative of flip-flops. In this paper, low power multi-bit pulsed-latches are proposed to construct pipeline stages in synchronous digital circuits. A method of integrating the proposed multi-bit pulsed-latches in the commercial design flows is also introduced. With the multi-bit pulsed-latches, up to 45% power savings are achieved for a variety of ITC benchmark circuits and an ARM Cortex-M0 as compared to the flip-flop based designs in an industrial 28-nm FDSOI CMOS technology. Furthermore, the power consumption of the clock distribution network and the layout area are reduced by up to 83% and 16%, respectively, with the proposed multi-bit pulsed-latches as compared to the flip-flop based designs.
