Hi
I have problems with modeling LM741 in Pspice...
I captured its schematics exactly similar to what is in gray's book but it doesn't work all the transistors are saturated!!!
looking forward for your helpful advises
 
is it necessary that the modelling has to be done in Pspice??
use software named MultiSim by National Instruments.
It is more user friendly compared to Pspice.
I have worked on both Pspice and MultiSim, so I m giving you the advice.
still if you are in a compulsion or something to model it in Pspice then please post your schematics.
 

Devil, can you please explain/describe which features in PSpice are less user friendly if compared with Multisim?
Because I cannot agree (I also have worked with both) - on the other hand, I think it is a matter of accustoming.

Hi Mona,

You are going to create a transistorized 741- model, right?
In this context, perhaps it is interesting for you that there are already such models available in (at least) two simulation packages: LTSpice (from Linear Technology Inc.) as well as Microcap (spectrum-soft.com).
