How to change the gain of Op-Amp for any Schematic Circuit of Op-Amp...?

Gain of Op-amp depends on the feedback resistor, so by changing the value of feedback resistor you can change the gain.

That i know .... But I m talking about internal parameters of Open Loop gain which should be ideally 200e03 but when i m doing schematic builder during that time how to change that gain ...?

Hi, you can change the value of Ein1 in the subcircuit of ua741. It is currently 100k, you can "Edit the value" and make it 200k.

You need to add ua741 from the linearSpice library, to your schematic. Then click on subcircuit builder and import "ua741". After importing it, click on Open and type ua741. You will get the schematic of Opamp ua741. Here you can edit the value of Ein1 (you might have to load Oscad libraries once again). Then follow the usual procedure of netlist creation, netlist conversion and simulation. Hope this helps.
