Modeling LM741

[mona:)]

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

Can you post a screen capture of your schematic in Pspice?

 

[DEVIL]

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).

Here is a good model of the 741. Why are they still teaching this old POS anyways?
