differential design, common mode noise rejection
I'm busy with a real differential pre-amp design. In fact four amplifier stages. one plus and one minus per channel.
If I fed a real balanced signaal through those stages, the real common mode happen at the poweramplifier side and not in the pre-amp.
I want to have a common mode already at the input of my pre amplifer. So what to do. I don't want a opamp in the input that's makes the signal unbalanced to make it balanced later. So I was thinking about (for example) a Jensen input tranformer direct after the balanced input, direct followed by the amplifer stages.
