This circuit gives closed-loop gain of R2/R1 when this ratio is small compared with the amplifier open-loop gain and, as the name implies, is an inverting circuit.

顾名思义，在R2/R1的数值远小于运放开环增益时，这个数值就是反相放大器的增益。

This circuit gives a closed-loop gain equal to the ratio of the sum of R1 and R2 to R1 and a closed-loop 3 dB bandwidth equal to the amplifier unity-gain frequency divided by the closed-loop gain.

和反相电路相比，其最大的不同点在于，其输出信号和输入信号是同相的，其输入阻抗也是相当高的，为 OP 差模输入阻抗与环路增益的乘积(环路增益为：开环增益/闭环增益)。
