本文介绍一种由不需严格挑选的分立元件及通用运算放大器构成的长时间低漂移直流积分器,着重分析了影响该积分器积分漂移的主要因素,并提出了抑制和降低积分漂移的措施.
In this paper, we introduce a long-time low-drift DC integrator composed of discrete components and general-purpose op amps that are not subject to rigorous selection. The main factors that affect the integral drift of the integrator are analyzed emphatically. Measures to suppress and reduce the integral drift are also proposed.
