一、诸言在最近几年来。在线电路参数的测量已成为现代重要的研究课题。尤其是在混合集成电路的制造与测试以及印制电路板的测试中参数的测量更是如此。文献[1]、[2]报导了适用于测量任意结构的阻抗网络电阻的在线测量的简单电路。但是报导在线电容的测量还鲜为人知。文献[4]报导了电容在线测量方法,它根据巴克哈森(Barkhausan)准则启动振荡。 First, the words in recent years. Measurement of online circuit parameters has become an important modern research topic. This is especially true for the measurement of parameters in the manufacturing and testing of hybrid integrated circuits and in the testing of printed circuit boards. Literature [1], [2] reported a simple circuit suitable for on-line measurement of impedance network resistance of arbitrary structure. However, it is still not well known to report on-line capacitance measurements. Literature [4] reported on-line measurement of capacitance, which started oscillation according to the Barkhausan criterion.
