This paper presents the adiabatic logic called 2[Formula: see text]–[Formula: see text]–2[Formula: see text], which can operate with less number of transistors and high energy efficiency than the existing circuit styles. It is a dual rail logic operated by four-phase power clock (PC). The 2[Formula: see text]–[Formula: see text]–2[Formula: see text] adiabatic logic is capable of operating through a wide range of frequency from 100[Formula: see text]MHz to 1[Formula: see text]GHz. Relentless scaling of MOSFETs towards lower technology nodes results in short channel effects in addition to increasing higher leakage current issues. In this scenario, FinFET advantageously replaces MOSFET with its unique features of the elimination of the short channel effects encountered by the MOSFETs with its gate structure that wraps around the channel completely. It incurs that the lower energy consumption and the feasibility of designing energy recovery circuits using FinFETs are analyzed in this paper. Comparatively, the energy efficiency of FinFET-based 2[Formula: see text]–[Formula: see text]–2[Formula: see text] against the [Formula: see text] and Positive Feedback Adiabatic Logic (PFAL) are analyzed. Simulation results also validate the robustness and efficiency of 2[Formula: see text]–[Formula: see text]–2[Formula: see text] adiabatic logic circuit under process parameter variations of FinFET technology. Complex adiabatic adders and multipliers taken as bench mark circuits have been designed using 32-nm FinFET technology node and the results validate the enhanced energy efficiency characteristics of 2[Formula: see text]–[Formula: see text]2[Formula: see text] over [Formula: see text] and PFAL designs.
