In today's VLSI design, static or leakage power consumption is a crucial metric due to component shrinkage. This research proposes and compares a 10 -transistor 1-bit complete circuit to alternatives that employ 20 and 14 transistors. Microwind 3.1, a CAD program, was utilized for every circuit simulation. Reductor layout for feature size The 90nm technology has been applied to determine the values of certain parameters. The energy efficiency of the suggested 10 -transistor complete subtractor is higher than that of its competitors.
