AND Logic Implementation Using Diodes

Description

A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels. There are various types of logic are available like AND logic, OR logic, etc. Here we have implemented two inputs one output AND logic. In this logic, the output is high only when both inputs are high, otherwise, the output remains low.

The Logic Implementation Using Diodes Circuit is easy to understand. Two diodes are used here. We know that the turn conducts only when the anode is at a lower voltage than the cathode. If one of the switches is on, then the diode corresponding to that switch conducts, and the voltage at v2 remains low. If both switches are off (open) then only the voltage at v2 goes too high and the LED gets to turn on.
