Summary: 
A new low power edge-triggered and logic embedded flip-flop based on complementary pass transistor circuit is proposed. This flip-flop provides small clock load, short propagation delay, single-phase clock scheme and small layout area. The flip-flop can reduce 35.2% power consumption while improving 24.7% propagation delay in comparison to conventional transmission-gate master-slave flip-flop in a standard 0.35 µm CMOS technology at 1.5 V power supply. In addition, logic functions can be embedded in the flip-flop. In 2-inputs multiplexer and flip-flop circuit, the proposed circuit can reduce 28.0% power consumption and improve 20.3% propagation delay compared to conventional circuit.
