Design Multipurpose Circuits with Minimum Garbage Outputs Using CMVMIN Gate

Abstract EN

Quantum-dot cellular automata (QCA) suggest an emerging computing paradigm for nanotechnology.

The QCA offers novel approach in electronics for information processing and communication.

QCA have recently become the focus of interest in the field of low power nanocomputing and nanotechnology.

The fundamental logic elements of this technology are the majority voter (MV) and the inverter (INV).

This paper presents a novel design with less garbage output and minimum quantum cost in nanotechnology.

In the paper we show how to create multipurpose reversible gates.

By development of suitable gates in logic circuits as an example, we can combine MFA and HS in one design using CMVMIN gate.

We offer CMVMIN gate implementations to be used in multipurpose circuit.

We can produce concurrent half adder/subtractor and one bit comparator in one design using reversible logic gates and CMVMIN gates.

Also, a 2×4 decoder from recent architecture has been shown independently.

We investigate the result of the proposed design using truth table.

A significant improvement in quality of the calculated parameters and variety of required outputs has been achieved.
