I have a homework problem with the following circuit:
I have solved the transistor biasing part and then drawn the AC-circuit of it. Then I need to find the transfer function.
These are the calculations I did:
This is the drawing which I drew by hand of what I think the transfer function will be:
I am not sure how we ended up getting infinite for the third case. Would really appreciate some help regarding this.
Similar problems like this I want to be able to solve in just some piece of paper.
