EXPERIMENT 1: BJT FIXED BIAS CONFIGURATION

1.0 Theory of the experiment

BJT Fixed Bias Circuit Configuration


A transistor is a semi-conductor device that can be used as an amplifier or a switch. It has 3
terminals. A BJT, standing for Bipolar Junction Transistor, is a type of transistor. A BJT has
three terminals called emitter (E), Base (B), Collector (C). BJT transistors can be PNP or
NPN. Biasing is the process of setting the DC input voltage of a transistor to a level so that
any ac
