A novel 32-bit adder has been designed using a Conditional Sum Adder (CSA) architecture and CPL-like logic implementation. The new implementation outperforms several architectures such as CLA, CS and Manchester which use the CMOS circuit styles (CPL, DPL, TG, static-conventional) in terms of power and speed. This is verified for a range of power supply voltage from 3.3 V down to 1 V. The comparison is carried out for two designs, minimum size and optimized speed.
