Pipelined GaAs carry lookahead adder

Abstract

Based on the recently introduced GaAs pseudo-dynamic latched logic, the authors present a new type of carry lookahead adder (CLA) which combines the benefits of 0.6 /spl mu/m E/D MESFET technology with the above mentioned class of logic. Consideration is given to power dissipation, taking into account that for high levels of integration, techniques to reduce the power budget are essential. As a result. The design of a four bit pipelined GaAs CLA operating at 800 MHz and exhibiting less than 1.8 mW of power dissipation is presented.
