And Gate Transistor Circuit. Both transistors must be saturated on for an output at q. This article will explain to you how to build and gate circuit using transistor.
Two input and gate using transistor the bc547 is used here in common emitter configuration. In the common emitter configuration transistor gives a phase shift of 180 degrees. When the base emitter diode is turned on enough to be driven into saturation the collector voltage with respect to the emitter may be near zero and can be used to construct gates for the ttl logic family.
The circuit symbol for each of them can be seen below.
2x 10k ohm resistors. The circuit symbol for each of them can be seen below. 1x led any color red was used in this project 1x 1k ohm resistor. But if either of the inputs are forced to logic low 0 the output will be forced to a logic low 0.
