P Jegadeeshwari, T. Anitha, M. Arulaalan · 2022
In this paper, design, layout, and successful simulation of a Digital Pulse Width Modulator in QCA is presented. Due to its extraordinary feature of small size and congruent power consumption, Quantum-dot cellular automata (QCA) has become one of most rapidly expanding nanotechnology research field and has endured a lot of attentiveness within engineering community in comparison with CMOS technology. According to reports, Quantum Dot Cellular has high device density and also has a low power consumption. Unlike traditional computers, which transport data by sending an electrical current from one location to another, QCA sends data by generating a polarization state. Several researchers have been employing QCA to investigate very complex circuit topologies in recent years. The architecture of Quantum Dot Cellular Automata for counter based Digital Pulse Width Modulation is presented in this brief. The counter and comparator circuits are included in the planned counter based Digital Pulse Width Modulation.
