A new design for programmable logic array based on QCA-based nanotechnology

Abstract

Dissipation in the complementary metal-oxide-semiconductor circuit size range has become a challenge for designers seeking to create a circuit with low power consumption and significantly reduced size. As a result, there is a need for an alternative technology that may provide revolutionary results. The quantum-dot cellular automaton is now widely regarded as a viable alternative to complementary metal-oxide-semiconductor technology. This paper demonstrates a new circuit for constructing a quantum-dot cellular automaton-based programmable logic array. The programmable logic array is a promising, standard, and fully programmable architecture that can use redundancy to make circuits with nanoscale feature sizes more practical. The comparisons based on cell number, size, and clock phases were made between the proposed circuit and previous ones using the QCADesigner. These comparisons verified the efficiency of the proposed design. The suggested programmable logic array circuit consists of 26 cells and occupies 0.04 µm2. In addition, the quantum cost of this circuit is 2.08, and the area delay is 0.08.
