Logic XNOR Gate Circuit with Transistors

Last updated on 24 June 2026 by Admin-Lavi Leave a Comment

XNOR gate is one of the basic logic gates, as it gives HIGH output when both inputs are same. If both inputs are 0 or both are 1, the output becomes 1 and if one input is 0 and the other is 1, the output becomes 0; for this reason, the gate is also referred […]
