how do you calculate midband gain

by Donny McKenzie Published 3 years ago Updated 2 years ago

As the frequency rises, the gain of the signal gradually goes up and up is calculated using Mid band gain = Load resistance / ( Load resistance + Emitter Resistance + Signal Resistance / ( Common emitter current gain +1)).

How to Calculate the Midband Gain of a Transistor Circuit

AC Analysis.
Solve R1||R2 (which is RB) The first thing to do is solve for RB:
Solve for RB|| RB' Next, after you get the value for RB, solve for RB', which is RB||rπ:
Solve for Output Resistance RL' ...
Solve for Vπ

Full Answer

Midband gain of emitter follower Solution

Load resistance - Load resistance is the resistance value of load given for the network. (Measured in Kilohm)

How does a emitter follower work?

As the amplifiers output signal is taken from across the emitter load this type of transistor configuration is also known as an Emitter Follower circuit as the emitter output “follows” or tracks any voltage changes to the base input signal, except that it remains about 0.7 volts (VBE) below the base voltage.

How to Calculate Midband gain of emitter follower?

Midband gain of emitter follower calculator uses Mid band gain = Load resistance/ (Load resistance+Emitter Resistance+Signal Resistance/ (Common emitter current gain+1)) to calculate the Mid band gain, The Midband gain of emitter follower formula is defined as 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.
