Low Power and Less Delay Circuit Shared Static Flip-Flop (LDCSSFF) for Digital Applications

Abstract

A modified flip flop for high speed and low power digital applications is designed. The proposed less delay circuit shared static flip flop (LDCS2FF) includes five number of NOR gates and back-to-back inverters. The inverter is given with a clock signal and the following signal is given as input to the NOR gates. The proposed LDCS2FF is a master slave flip flop act as a storage element. The proposed LDCS2FF is simulated on Synopsys tool HSPICE under 32 nm BSIM4 model card for bulk CMOS technology of PTM model. The proposed LDCS2FF as 24 transistors with delay of 0.3 ns at 1 V applied voltage and power dissipation of $59.6\ \mu\mathrm{W}$ at 0.8 V applied voltage.
