A COMPARATIVE EVALUATION AND ANALYSIS OF D FLIP FLOP FOR HIGH SPEED AND LOW POWER APPLICATION

Abstract
This paper presents comparative analysis of various flip-flops in CMOS technology. We simulated dual dynamic node hybrid flip flop (DDFF), Hybrid latch flip-flop (HLFF), Modified hybrid latch flip flop (MHLFF), and modified transmission gate flip flop (TGFF). The average power of various flip flops are calculated at 0%, 25%, 50% and 100% data activity, at temperature 25-100 ÂșC and different voltages 0.7, 0.9, 1 and 1.5. The average delay is also calculated at room temperature. All of these parameters are calculated in 32nm CMOS technology with the help of TSPICE. It was observed that MHLFF is the flop-flop that consumes less power compared to other flip flops. We are comparing performance and power dissipation and also compared transistor count of each flip flop.
