“…The existing positive feedback leads to stronger polarity and signal injection [28]. However, as also mentioned in [13], this effect is more pronounced in multi-layer circuits and, in general, is neglected in previous works due to the lack of an appropriate noise model in QCA and the suitability of the transmitted signal shape. In this paper, due to adherence to design rules and appropriate clocking of the designed structure, as seen in Figures 5, 7, 9, 10, 11, and 13 the responses appear acceptable.…”

This paper presents a Modified Gate Diffusion Input (MGDI) design with four inputs for Quantum-dot Cellular Automata (QCA) technology. QCA is a promising nanotechnology that offers benefits such as low power consumption, and high density, making it a potential alternative to CMOS technology. The proposed planar cell design has advantages over previous designs, including a 19% reduction in the number of cells, a 29% reduction in total energy consumption, and a 44% reduction in average energy loss at the same occupancy level. The proposed block is capable of implementing 21 basic combinational functions and various sequential functions. The simulation of functions in 18nm technology and energy consumption calculation indicates that the resulting circuits have improvements of 41%, 27%, 27%, and 20% compared to multiplexers, comparators, four-bit parity circuits, and single-bit memory, respectively. Additionally, the number of cells in the proposed circuits has improved by 10%, 7%, 22%, and 19%, respectively.
