hi ....

I was reading through my book and could understand the difference between "terminal voltage gain" and "overall voltage gain"
BJT single stage amplifiers

 

Can you show as the diagram or the text from that book.
General speaking when we treat the amplifier alone the the voltage gain is equal
Av = Vout/Vin

But if we consider the influence of the source resistance and input resistance of our amplifier we get the overall gain.

Overall gain = Vout/Vs = Vin/Vs * Vout/Vin = 0.5 * 100 = 50V/V

 

Thanks...it was helpful

 

hi ....

I was reading through my book and could understand the difference between "terminal voltage gain" and "overall voltage gain"
BJT single stage amplifiers

terminal voltage gain refers to V (collector ) / V ( base)= Beta
Overall voltage gain refers V ( out) / V( in)
It is the matter of the fact that at which terminal or branch you take the measurements

Correct me if i am wrong

Lazukan

 

Terminal gain refers to β gain (Hfe) which we can directly measure on
Multi-meter.
While overall voltage gain refers to, taking gain with taking source Impedance and Load impedance into consideration

 

β is a measure of current gain: it is not directly related to voltage gain, although due to its effect on input impedance it does make a contribution to overall voltage gain.

 

yeah ur right i realized my mistake
Thank u
