Abstract

A simple procedure to evaluate the energy consumption of adiabaticgate circuits is proposed and validated. The proposed strategy isbased on a linearization of the circuit and simplifying theanalytical result obtained on the equivalent network. The approachleads to simple relationships which can be used for apencil-and-paper evaluation or implemented on software. Theaccuracy of the results is validated by means of Spice simulationson an adiabatic full adder designed with a 0.8 μm technology.
