CMOS XNOR Gate

Question

Problem: CMOS XNOR Gate. Solve this hands-on electronics task on EWskills.

Accepted Answer

The CMOS inverters generate A' and B'. Two transmission gates select either B' or B based on input A.

Therefore, Y becomes HIGH only when A and B are equal.

Y = A' · B' + A · B = (A ⊕ B)'
