摘要
本文分析了电荷放大器零点漂移的根源,影响零点漂移的因素及漂移规律。从理论上证明可通过补偿的方法消除零点漂移,进而提出通过反馈补偿网络消除零点漂移,并通过实验证实了上述方法。
This paper analysed the origin and the factors which causa and affect the zero drift of charge amplifier, as well as the rule of the drift. It has been proved in theory that the drift can be eliminated. To achieve this, a method using a feedback compensated network in the circuit has been developed, and the experimental results are consistent vrith the theory
