The voltage gain of an amplifier is determined by several key factors, including the amplifier's design and configuration (such as common emitter or common source), the values of its components (like resistors and capacitors), and the characteristics of the active devices (transistors or operational amplifiers) used. Feedback mechanisms, both negative and positive, can also significantly influence the gain by stabilizing or enhancing it. Additionally, the load impedance connected to the amplifier affects its voltage gain, as it interacts with the output stage of the circuit.

What is the voltage gain of a transistor amplifier that has an output of 5 rms and an input of 250 mV rms?
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.

What is stage gain in a C-E amplifier?
Stage gain in a common-emitter (C-E) amplifier refers to the amplification factor of the input signal as it passes through the amplifier stage. It is typically defined as the ratio of the output voltage to the input voltage, expressed as a voltage gain (Av). In a C-E configuration, the stage gain is generally greater than one, indicating that the output signal is amplified relative to the input. The gain is influenced by factors such as the transistor's characteristics, resistor values, and the load connected to the output.

What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
Why does amplifier gain reduce?
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases

What is voltage follower?
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
