Design and Performance Analysis of MZI Based 2×2 Reversible XNOR Logic Gate

In this article, first the model of 2×2 reversible logic gate is proposed after then the performance of the proposed designed is evaluated. With the increasing flow of information, data rate is increasing very rapidly. This has resulted in increased amount of heat dissipation from the processing nodes. Generally, electronic processors dissipate heat if the data rate is very high. Hence, this model will be very helpful for solving this problem. Evaluated performance of this model is based on the value of quality factor and extinction ratio. The quality factor and extinction ratio are evaluated under different conditions. The average extinction ratio of the design is 19.58 dB and the average quality factor is 53.03 dB. The optical cost of the proposed circuit is 1.
