As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates ... logic was replaced with diode and transistor logic. This represented a ...

If A=B, Cout = B If A ≠B, Cout = Cin Equality of A and B can be checked by XNOR gate as it gives a logic high when both inputs connected to it are same. A transmission gate consists of a PMOS and NMOS ...
