Abstract


In this paper, Positive Feedback Source Coupled Logic (PFSCL) based asynchronous pipeline implementation is addressed. Existing Conventional PFSCL and a more efficient Triple-Tail Cell-based PFSCL variant are used for this purpose. Striking a trade-off between both topologies, a new hybrid implementation of the pipeline has been proposed. The concept is elucidated through FIFO sequencer. The hybrid implementation of asynchronous pipeline results in lesser number of gates as well as lower average power dissipation, thus not only making the circuit more efficient but also reducing overall area overhead. The validity of the proposal is confirmed through SPICE simulations using 0.18 um CMOS technology parameters.

In this paper, to design a number of D-flip flop performing at the same time, the given clock signal is reduced using multi bit flip-flop. The multi bit flip flop is mainly used to improve the clock power for the given common clock signal and to reduce the switching power. This method is p...
