  • Abstract
    This paper describes the design of a standard cell library of differential mode threshold gates, referred to as a Threshold Logic Latch or TLL, and new threshold function identification and decomposition methods to map a conventional logic network consisting of logic gates and flipflops, into a hybrid network that consists of both TLLs and conventional logic gates. After logic synthesis and physical design (placement and routing) using a commercial 65nm LP (low power) library, and commercial design tools, the hybrid circuits are shown to have up to 35% less dynamic power, about 50% less leakage power and around 37% less area when compared to the corresponding conventional design operated at the same (peak) frequency.
