The increasing demand for efficient signal processors necessitates the design of digital finite duration impulse response FIR filter which occupies less area and consumes less power. FIR filters have simple, regular and scalable structures. This paper represents designing and implementation of a low-power 4-tap FIR filter based on quantum-dot cellular automata (QCA) by using a realistic clocking scheme. The QCADesigner software, as widely used in QCA circuit design and verification, has been used to implement and to verify all of the designs in this study. Power dissipation result has been computed for the proposed circuit using accurate QCADesigner-E software. The proposed QCA FIR achieves about 97.74% reduction in power compared to previous existing designs. The outcome of this work can clearly open up a new window of opportunity for low-power signal processing systems

Quantum-dot cellular automata (QCA) technology is one of the emerging technologies that can be used for replacing CMOS technology. It has attracted significant attention in the recent years due to its extremely low power dissipation, high operating frequency, and a small size. In this study, we demonstrate an n-bit parity generator circuit by utilizing QCA technology. Here, a novel XOR gate is used in the synthesis of the proposed circuit. The proposed gate is based on electrostatic interactions between cells to perform the desired function. The comparison results demonstrate that the designed QCA circuits have advantages compared to other circuits in terms of cell count, area, delay, and power consumption. The QCADesigner software, as widely used QCA circuit design and verification, has been used to implement and to verify all of the designs in this study. Power dissipation has been computed for the proposed circuit using accurate QCAPro power estimator tool.

Quantum dot cellular automata (QCA) is a hopeful technology in the field of nanotechnology that seems to suite well with signal-processing needs. It is concerned with great interest because of its benefits such as ultra-low power consumption, small size and can operate at one Terahertz. The multiply accumulator (MAC) unit is considered as one of the essential operations in digital signal processing (DSP). In the real-time DSP systems, several applications like speech processing, video coding, and digital filtering etc. require MAC operations. However, the power dissipation and area are the most significant aspects in these systems. Here, the authors design low power MAC unit based on QCA technology. QCADesigner version 2.0.3 is used to validate the accuracy of the proposed circuit. The reliability of this unit is taken at different temperatures. The power dissipation is estimated using QCAPro tool. The total power consumed by this unit is 2.183 μW. The proposed circuit has 90% improvement in terms of power over complementary metal-oxide-semiconductor (CMOS) circuits. Since the works in the field of QCA logic signal processing has started to progress, the suggested contribution will give rise to a new thread of research in the field of real-time signal and image treatment.
