Adiabatic Logic: A Paradigm Shift in Power-Efficient VLSI Design for FIR Filters

In the realm of VLSI (Very Large Scale Integration) technology, power consumption is a criticalchallenge that demands innovative solutions. This research focuses on the implementation and analysis of adiabatic logic as a method to significantly reduce power dissipation in digital circuits, particularly in Finite Impulse Response (FIR) filters. Adiabatic logic operates on the principle of energy recovery, leveraging adiabatic processes to conserve energy within a closed system. Key solutions such as Clock Gating, Power Gating, Multi-Voltage Design, and Voltage Scaling have been effective in managing power consumption; however, adiabatic logic emerges as a promising contender due to its ability to achieve substantial reductions in power consumption. The basic building blocks of arithmetic logic are implemented in adiabatic logic and verified for power reduction and then it has been extended to the design and integration of adiabatic logic into FIR filters, meticulously evaluating power consumption as a primary metric throughout the exploration process. Statistical analysis comparing power dissipation between adiabatic logic and conventional CMOS logic for FIR filter designs revealed a remarkable reduction of approximately 66.6
