Design and Analysis of Power and Area Efficient 4–2 Compressor Circuit for Tree Multiplier

Power efficiency is essential in contemporary digital circuit design due to the growing demand for energy-efficient electronics. Multiplication procedures increase the demand for efficiency in applications like arithmetic and signal processing. For quick and accurate calculations, tree multipliers, which are frequently used in these jobs, largely rely on 4–2 compressor circuits. This paper analyses the theory, operation, and mathematics of a 4–2 compressor architecture for tree multiplier. The design drastically reduces power while retaining logic behaviour by utilizing strategies such as AVLS, Lector, Adiabatic etc., It exhibits about 35.18% greater power efficiency than conventional design, according to experimental validation. The study goes so far as to incorporate this power-saving circuit into tree multipliers, which offers power savings and performance preservation. This work lays the groundwork for future improvements to digital systems while simultaneously addressing circuit power problems.
