Formulas to find Gain Factor

Amplifier Gain in Mid Band

Amplifier Gain in Mid Band is a measure of the ability of a two-port circuit to increase the power or amplitude of a signal from the input to the output port.

Symbol: A_m

Measurement: SoundUnit: dB

Note: Value should be greater than 0.

Formulas to find Amplifier Gain in Mid Band

Mid Band Gain

The Mid band Gain of a transistor is the transistor's gain at its mid frequencies; the mid band gain is where the transistor's gain is at the highest and most constant level in its bandwidth.

Symbol: A_mid

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.
