A sub-10-ns 16×16 multiplier using 0.6-μm CMOS technology

A 16×16-b parallel multiplier fabricated in a 0.6-μm CMOS technology is described. The chip uses a modified array scheme incorporated with a Booth´s algorithm to reduce the number of adding stages of partial products. The combination of scaled 0.6-μm CMOS technology and advanced arithmetic architecture achieves a multiplication time of 7.4 ns while dissipating only 400 mW. This multiplication time is shorter than other MOS high-speed multipliers previously reported and is comparable to those for advanced bipolar and GaAs multipliers.
