TG Master-Slave FFs: High-speed optimization

Abstract

In this paper we show that, when dealing with transmission−gate based Master-Slave FFs, a reconsideration of the usual approach for high-speed design is worthwhile to improve energy-efficiency. By splitting such FFs in two separately optimized sections and then reconciling the results, the emerging design always outperforms that resulting from the employment of a classical procedure assuming FFs as a whole continuous path.
