After basic mathematical operations i.e. Addition, subtraction, multiplication, and division, square root is regarded as the most useful and applicable operations in scientific calculations. There are various methods for hardware implementation of square root. One of the most common methods in this field is non-restoring algorithm. In this paper, the improved classical non-restoring array structure is successfully designed and implemented by Quantum-dot cellular automata technology in a single layer scheme. In order to accomplish a high performance square root circuit, our proposed design is leveraged using Nanoelectronic-compatible elements. The simulation results achieved from QCA Designer tool authenticate the correct functionality of the proposed structure.
