摘要：

In the GIS detection system, the signal which is detected by the charge amplifier often contains much common mode interference. So the charge amplifier used can't meet the requirement. Based on this problem, this paper designs a three op amp differential amplifying circuit which can restrain common mode signal effectively and has a wide operating frequency. The circuit can restrain common mode signal in GIS flash over fault effectively which is verified by simulating the circuit with Multisim and testing the hardware circuit.
