This paper proposed the design and implementation of a 2-input XOR gate using 4- transistor. 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. 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).
