Performance Optimization of Johnson Counter Using SSASPL

Paper proposes Johnson counter utilizing pulse latches to build execution parameter of past counter. A Johnson counter is an altered ring counter in which the changed yield from the final flip stoop is related to the contribution to the primary. To decrease region flip flop are supplanted by pulsed latches. A latch continues checking its sources of info and changes its yields individually. The latch can send or get the information just if switch is on and principle factor is that it relies upon the length of duration of pulse. pulse latches are littler than flip flops, in this way they requires little area consequently in numerous applications latches are utilized as a part of place of flip-flops. A counter is one of its real applications. Number of flip-flops associated in arrangement one back another to manufacture a counter. Counters are a famously utilized segment in computerized circuits and additionally are made as isolated coordinated circuits and furthermore inundated as parts of greater incorporated circuits. Counters can be manufactured effectively utilizing register sort circuits, for example, the flip-flop. This strategy utilized the latch for outline of Johnson counter. We progressed our brig about terms of transistor be counted and power dissipation as compared to preceding designs. This process is done by using 0.18um CMOS process with V_DD =2V.
