Abstract :
In this article, we have designed a novel 4:2 QCA Compressor with a nonlinear effect. This can be considered as a new vision to design approximate Majority circuits with more than five-input. The main advantages of these ideas are the reduced number of QCA cells as well as power dissipation, increased speed, and improved cell area In addition, a novel hierarchy is introduced to optimize digital systems. The 4:2 Compressor circuit is selected as a benchmark. This circuit is simulated with some technologies such as CMOS, CNT, and QCA in different architectures. All results from power respective were compared. We have used QCADesigner and QCAPro for QCA Circuits, Hspice with 20nm-nfet PTM-MG model for CMOS circuits and Stanford CNFET 20nm model for CNT circuits as simulation tools to evaluate circuits.
