✦ Synopsis

Arithmetic circuits have always played one of the most important roles in the designs of processors, FPGAs, and the rapidly evolving domain of media processing architectures. The full adder cell forms the basic building block of majority of these arithmetic circuits. In this paper we describe a hybrid pseudo static full adder cell designed using Data Driven Dynamic Logic. Simulation results show the adder to out perform its competitors, both static as well as dynamic topologies in terms of performance, while maintaining relatively similar area and power characteristics. This paper presents a complete characterization of the popular adder cells in terms of delay, area, power, noise margin and reliability analysis for both super threshold and sub threshold operating regimes.
