英文摘要：

The non-inertia integration circuit is a basic link in the reduction of DC or low-frequency small signal.The problem of zero drift is directly related to whether the circuit can work normally or not.A certain noninertia integration circuit is studied in detail,a zero drift automatic suppression technology based on C8051 F350 MCU is proposed to deal with the drift voltage from the operational amplifier input by injecting the suppression signal into the input directly.This technology is designed to ensure that the integration circuit can work accurately for more than 10 s.The experiment results show that the technology is effective and feasible.
