摘要
I present a new design for a 1-bit fiíll adder featuring hybrid-CMOS design style. Our approach achieves low-energy operations in 90nm technology. Hybrid-CMOS design style makes use of various CMOS Iogic style circuits to build new íull adders with desired specifícations. The new SERF- füll adder (FA) circuit optimized for ultra low power operation is based on modifíed XOR gates with clock gating to minimize the power consumption. And also generales full-swing outputs simultaneously. The new full-adder circuit successfuUy operates at low voltages with excellent signal integrity. The new adder displayed better power and delay metrics as compared to the standard íull adders. To evalúate the performance of the new full adder in a real circuit, we realized 4-2,5-2,5-3,7-2,11-2,15-4,31-5 compressors which are basically used in multiplier modules of DSP filters. Simulated results using 90nm standarad CMOS technology are provided. The simulation results show a 5% - 20% reduction in power and delay for frequency 50MHz and supply voltages range of 1.1 v.
