BJT as an Amplifier - The Engineering Knowledge
https://www.theengineeringknowledge.com/bjt-as-an-amplifier/
From this equation, you can see that the bjt used in circuitry gives amplification in the shape of voltage gain that is dependent on the values of RC and r’e. As RC is always significantly higher, the output voltage for this arrangement is larger than the input voltage. So, friends, it is a complete post about BJT as an amplifier.

The stage gain of a BJT, used as a simple amplifier, can be determined from the relationship: V out / V in = h fe R L / ( R S + r i ) where R S is the source resistance, R L is the collector load resistor, h fe is the small-signal (AC) current gain, and r i is the internal emitter-base resistance of the transistor.

sistor (BJT) circuits are used as small-signal amplifiers. The term small-signal refers to the use of signals that take up a relatively small percentage of an amplifier’s operational range. Additionally, you will learn how to reduce an ampli-fier to an equivalent dc and ac circuit for easier analysis, and you will learn about multistage amplifiers.
