Abstract

An improved design of a hybrid latch flip-flop is presented. The proposed design overcomes the problem of the glitch at the output and reduces the power consumption and delay of the circuit resulting in a total power-delay-product improvement of about 20%. It also exhibits better soft-clock edge properties compared to the original circuit. This is accomplished by careful design of keeper elements and introducing the feedback path to suppress unnecessary transitions in the circuit. The new design introduces an insignificant area increase.
