Inverse proportion basic circuit diagram
1. The basic circuit: Voltage series negative feedbackThe input end is virtual short, virtual-off The features: Reverse side is the virtual ground, so the common mode input can be regarded as 0, the CMRR on the op amp requires low. The output resistance is small with a strong load capacity When it requires a large magnification, the feedback resistor is high, the stability is poor. If the required magnification is 100, R1 = 100K, Rf = 10M. (View)
