Abstract :
A fast 64-bit dynamic adder has been designed for high performance microprocessors in 2.5-V 0.25-μm 1-poly 5-metal CMOS technology. Fast carry signals can only be obtained by fast G (Generation) and P (Propagation) terms. Integrating dynamic CMOS logic, the Kogge & Stone algorithm and a new circuit architecture, the adder comprises 7 k FETs and has 660 ps addition latency under nominal conditions
