op37闭环增益必须是5倍以上吗?作为射极跟随,放大一倍,不可以吗? ???
或者放大2倍不可以吗?
The gain must be 5 at high frequency for OP37. So you can just have a resistor in the feedback, like 100 Ohms, and then put 20 Ohms and 1nF or so from -in to ground.
Or, say if you're doing G=2 with 499 / 499, then just put 100 Ohms (or so) and 1nF from -input to ground.

如果在低频情况下,譬如20KHz以下的情况,我可以做射极跟随吗?也就是G=1可以吗? 直接将OP07的输出和输入负极连接在一起,输入正极作为信号输入,可以吗?
