This paper introduces and compares two topologies for the C-element in MCML and two topologies for double-edge-triggered flip-flop in MCML. Based on the simulation results, an asynchronous MCML C-element dissipates four times less power than conventional static CMOS C-element at the same throughout of 1.9 GHz. Also, MCML double-edge-triggered flip-flop runs up to three times faster than the conventional static CMOS counterpart at the same power level. All the circuits are implemented in a standard 0.18 μm CMOS technology.
