Differential gain is a measure of how an amplifier's output voltage changes in response to a change in input voltage. It is calculated by dividing the change in output voltage by the change in input voltage.
Differential gain = ΔOutput/ΔInput
If the input voltage is increased by a small amount, the output voltage will also increase by a small amount. The differential gain is the ratio of these changes in output voltage and input voltage.
Example:
Let's say an amplifier has a differential gain of 2. This means that for every 1% change in the input voltage, the output voltage will change by 2%.
Use Cases of Differential Gain:
Differential gain is used in various applications, including:
Amplifier stability: Differential gain helps to ensure that an amplifier remains stable over a wide range of input signal levels.
Filtering: Differential gain can be used to filter out unwanted signals by attenuating or blocking them.
Signal processing: Differential gain is used in signal processing techniques such as filtering and amplification.
