1. The basic circuit: Voltage series negative feedbackThe input end is virtual short, virtual-off The features: input resistance is high, output resistance is small, the load capacity is highV-= V + = Vi, so the common mode input is equal to the input signal, the common mode on the op amp's can suppress the ratio.
