Bjt Amplifier Circuit Diagram. Assume enforce analyze and check. In this circuit the base terminal of the transistor is the input the collector is the output and the emitter is common to both.
The term small signal refers to the use of signals that take up a relatively small percentage of an amplifier s operational range. In this circuit the base terminal of the transistor is the input the collector is the output and the emitter is common to both. A pnp schematic symbol b layout c npn schematic symbol d layout.
The bjt can be used as amplifier as well as a switch.
Mostly used for the conversion of audio signals to electronic signals as well as for current controlling circuits. The direction of the arrow always points from the positive p type region to the negative n type region for both transistor types exactly the same. It used in different electronic projects and circuits for switching and amplification process. In common base configuration bjt is used as voltage gain amplifier.
