一、前言大多数灵敏的电容测量仪都是利用阻抗测量技术,如交流电桥;或是利用振荡频率测量法,如 LC 振荡器来达到。Fielden 研制了一种应用电荷转移原理的
I. INTRODUCTION Most sensitive capacitive measuring instruments use impedance measurement techniques such as AC bridges, or oscillation frequency measurements such as LC oscillators. Fielden developed a charge transfer principle
