Flip flop using dual inverter feedback

Abstract

Embodiments of the present disclosure relate to a flip flop circuit that obviates the need of a transmission gate. The flip flop includes a first match multiplexer, a second match multiplexer and a separable inverter. The first match multiplexer receives an input data signal and generates a feedback output based on the input data signal and the logic levels at two nodes coupled to the first match multiplexer. The separable inverter receives the feedback output and switches the logic level of one of two nodes but maintains the logic level per each clock cycle. The second match multiplexer generates a signal output based on the logic levels at the two nodes and the signal output that is fed back into the second match multiplexer. Embodiments may reduce power consumption and operate at lower voltages.
