Abstract :
A new high-performance variable time adder is presented which is based on the statistical carry look-ahead addition technique. The new circuit uses carry-select stages to reduce the critical path. A 56 bit adder designed for and realised using 0.5 μm CMOS technology shows an average addition time of ~1.28 ns
