Differential Gain in BJT Differential Amplifiers Formulas

Differential Gain is defined as when a differential input is supplied i.e. input 1 is not equal to input 2. And is denoted by A_d. Differential Gain is usually measured using the Decibel for Noise. Note that the value of Differential Gain is always negative.

FAQ

What is the Differential Gain?

Differential Gain is defined as when a differential input is supplied i.e. input 1 is not equal to input 2. Differential Gain is usually measured using the Decibel for Noise. Note that the value of Differential Gain is always negative.

Can the Differential Gain be negative?

Yes, the Differential Gain, measured in Noise can be negative.

What unit is used to measure Differential Gain?

Differential Gain is usually measured using the Decibel[dB] for Noise. Neper[dB], MilliDecibel[dB] are the few other units in which Differential Gain can be measured.
