a robust, fast pulsed flip-flop design
High Speed VLSI design utilizes heavy pipelining, resulting in a large number of flip-flops in the circuit. Hence there is a strong motivation to design fast, low power and area efficient flip-flops. In this paper, we present a pulsed flip-flop design based on a novel pulse generator circuit. Our design achieves significantly improved speed when compared to recent pulsed flip-flop design, as well as a traditional master-slave D flip-flop. Monte Carlo simulations demonstrate that our design is significantly more robust to variations than the other flip-flops. Our design consumes low power as well. Also we have performed the layout of our design and shown that our layout area is smaller than a traditional D flip-flop.
