I designed the following 2T XOR cell for my full adder purpose:
Theoretically it gives correct output for all input combinations. But on Tanner Eda using 180nm technology 5V supply, it gives logic 1 for input combination a = 1, b = 1 but theoretically it is incorrect. Because PMOS OFF for input logic 1 so output must be zero.
How can I make my 2T XOR cell fully functional for all input combinations?
