Aim: This paper proposed the design and implementation of a 2-input XOR gate using 4-
Method: The XOR gate can be designed using NOT gate and 2:1 multiplexer. The NOT gate is designed
using two metal–oxide–semiconductor field-effect transistors MOSFETs and an approximate
2:1 multiplexer. The 2:1 multiplexer is designed using two MOSFETs. So, an XOR gate can be designed
using four transistors.
Results: The proposed work theoretically and experimentally describes the 2-input XOR gate using 4-
transistor. The proposed work was verified using Xilinx (ISE Design Suite).
