This paper presents the sub-threshold logic and standard cell library for it. Standard cell library consists of basic gates as well as universal gates (INVERTER, EX-OR, NAND, NOR gate) in sub-threshold logic. The components of this library can be used to design any complex combinational circuit utilizing less power as compared to super-threshold one. Impact of sizing of nmos and pmos is also given in this paper. There is also a comparison between sub-threshold and super-threshold logic.
