large signal analysis

Hi guys!

Can u guys tell me more? I know about small signal analysis well. But i dunno about large signal. Thank you!

Guys, my next question is when we apply large signal analysis, will the biasing for the mosfet be affected ? Does large signal analysis also affect dc analysis?

Large signal analysis

use .trans analysis

Large signal analysis

In large signal analysis your transistor has different mode and need to be considered.
you can google this

I am afraid both answers (see above) will not help too much.
Let me try it:
1.)For small signal analysis your circuit is assumed to be ideal and LINEAR ! Therefore, you can apply 1000 volts to the input of a transistor stage - and you get 50000 at the output (if the small signal gain is 50)
2.) For large signal analysis you have to call the TRANSIENT analysis. Now, all non-linear effects of the circuit (as far as they are modelled) are taken into account. As a result - you will see signal distortions and limiting effects due to the power supply rails.
