Area and power efficient FIR filter design in quantum cellular automata using competent adder

Abstract An 8-tap FIR filter is being considered for this research work. The basic modules of the FIR filter are Adders, Delay elements and multipliers. These basic elements are constructed using the majority voter. The interconnections between various logic elements of the circuit are carried out using novel multi-layer interconnection. Also, fast adders such as carry look-ahead adder, carry save adder, and carry select adder have been realized in quantum cellular automata. The circuit performance has been evaluated mainly based on the number of cells used for construction and area. Also additionally, area-latency product (ALP), QCA cost and power-performance area (PPA) have been estimated for validating the effectiveness of the design. Because of the majority voter and multi-layer configuration, the basic elements had occupied a lesser area; due to which the overall area for the 8-tap filter has been reduced effectively. The basic elements had a cell count improvement of 16.27% to 89.37% for full adder, 52.54% to 94.11% for DFF and 15.71% to 94.79% for multiplier with respect to the existing methods. Also, an 8-tap FIR filter consumes 2156 cells, 3447.6 nm 2 area, 36.0876 energy dissipation, 13790.4 ALP, and 124415.6 PPA in quantum cellular automata.
