Are you perhaps referring to different circuit analyses for transistors?Hello everybody,
What different between AC BJT &Amplifier BJT ?
Thanks sir,Hello full, have you got your maths problem solved now?
Are you perhaps referring to different circuit analyses for transistors?
We perform a static or DC analysis for the purpose of setting up the transistor biasing to the correct mean operating or Q point.
We can then perform an AC signal analysis on the transistor in its biased circuit configuration.
There are two forms of such analysis
Small signal analysis
and , yes you've guessed it,
Large signal analysis.
The reason that we have two is that transistors are not linear devices, wheich means that their properties (characteristics or parameters) change with the signal.
In a small signal analysis we assume this change is negligable.
In a large signal analysis we take it into account.
