Hi everybody,

I need to offer a circuit design with 20db fixed gain input stage and a >40 db variable gain. Input should have differential inputs and should implemented using FET's.

I looked in my textbooks, but I could not find any circuits, can you help me?

It does not need to have any strict bandwith and input impedance, I just need to offer something.

It would be great if anybody can help me.

Regards,
Targocid
