Low-Power Pulse-Triggered Flip-Flop Design With Conditional Pulse-Enhancement Scheme

V. Tholkappian, B. Karthick

Abstract


In this paper, a novel low-power pulse-triggered flip-flop (FF) design is presented. First, the pulse generation control logic, an AND func- tion, is removed from the critical path to facilitate a faster discharge oper- ation. A simple two-transistor AND gate design is used to reduce the circuit complexity. Second, a conditional pulse-enhancement technique is devised to speed up the discharge along the critical path only when needed. As a result, transistor sizes in delay inverter and pulse-generation circuit can be reduced for power saving. Various postlayout simulation results based on UMC CMOS 90-nm technology reveal that the proposed design features the best power-delay-product performance in seven FF designs under com- parison.
