Design and Performance Analysis of Adiabatic Logic Circuits Using FinFET Technology

Abstract

Power dissipation is now a major concern in large-scale integration (VLSI) design, particularly in high-performance, low-power applications, as semiconductor technology shrinks. Because of its reputation for energy harvesting, adiabatic logic provides a practical means of reducing the dynamic power consumption of integrated circuits. Unlike conventional planar MOSFETs, FinFET technology offers better electrostatic control, lower losses, and greater scalability. This paper proposes the design and performance analysis of adiabatic logic circuits using FinFET technology. The study applies FinFET technology at 22 nm and 14 nm process nodes to implement important adiabatic logic families such as adiabatic positive feedback logic (PFAL) and energy recovery logic (ECRL). The circuits are designed in a simulated manner and their performance is evaluated in terms of latency, power efficiency, and power dissipation in a standard Cadence environment. To demonstrate the benefits of FinFET-based adiabatic designs to achieve lower power consumption, a comparative analysis with conventional CMOS circuits is also depicted. FinFET-based adiabatic circuits are especially well-suited for low-power VLSI systems, as demonstrated by the considerable reductions in power dissipation and energy per operation found in the simulation results.
