Abstract :
A fast, low-power, and small 16-bit adder was fabricated using 0.25-/spl mu/m GaAs HJFET technology for future wireless video communication. This adder, which uses negative logic binary look-ahead carry (BLC) structure based on NOR gates, operates at the maximum clock frequency of 1.67 GHz and consumes 134.4 mW at a supply voltage of 0.6 V. The active area is 1.6 mm/sup 2/ and there are about 1,230 FETs.
