摘要
推出一种微小电容测量新电路,它可应用于1pF以下的微小电容测量,以及与微小电容检测有关的计算机辅助断层摄影技术或其它电容传感技术中。
A new circuit for small capacitance measurement is proposed in this paper, which is capable of measurement of capacitance less than 1 pF. It can be used in computer tomography and other capacitance sensor techniques related to measurement of small capacitance.
