The design and analysis of a multiplexer (Mux) circuit utilizing adiabatic switching techniques, specifically focusing on Energy Recovery Logic (ERL) and Charge Recovery Logic (CRL), with particular emphasis on the ECRL and PFAL families. The primary objective is to significantly reduce power dissipation by recovering energy during signal transitions, which would otherwise be dissipated as heat in conventional CMOS circuits. Adiabatic logic circuits achieve this by performing logic transitions at slow voltage rates, allowing for energy recovery through controlled voltage sources or inductive elements. This study investigates methods to maximize the energy recovery, optimizing the inclusion of components like inductors and capacitors to facilitate energy transfer, minimize losses, and enhance efficiency.

A key challenge is to maintain an optimal balance between slow voltage transitions—required for energy recovery—and the need for acceptable switching speeds that meet the requirements of modern digital systems. We present a design for an efficient adiabatic multiplexer that incorporates these principles, ensuring that the circuit is capable of low power operation while meeting performance constraints. Simulations are conducted to assess various metrics, including power consumption, energy recovery efficiency, and switching speed, and to validate the effectiveness of adiabatic switching techniques in real- world scenarios.
