Hello everyone.
We have been given a project in our electronics lab to create a voice amplifier using an op amp having gain 100. We first need do pspice orcad simulation. Can anyone give a general idea of what i need. And is there any mic model in default library?? if not please post a link to one..

Awaiting response...

The process usually works when you design ... and if you have questions, you post your design and the members will comment on your design. If it worked the other way, where the members designed and gave to you, you would be deprived of the pleasure and joy of learning.
