I keep running across the term Input Impedance and yes, I do know what impedance is. But I seem to be missing some nuance of it. Op Amps have near infinite Input Impedance and, If I understand it correctly, higher Input Impedance has some affect on amplification. But just how does it do so? From my experience, higher resistance/impedance attenuates so how does a higher Input Impedance lead to greater amplification or just what am I missing here?
