CMOS logic gates are basic building blocks for VLSI adder's circuits. The delay through these gates is related to their sizes and terminal loads. Logical effort is a technique, which gives insight about proper sizing of CMOS logic gates to have the minimum achievable delay. In this paper, the authors discuss first the technique of logical effort; three common architectures for VLSI adders are sized using logical effort to get the minimum possible delay. Simulated results are used to design fast CMOS circuits. A comparison between delays for these structures is presented according to simulation results in 32 nm standard CMOS process.
