摘要

开发了一种基于C8051F006 SoC的简单廉价的电容电压(C-V)表，用于表征电子元件。它可以作为实验室的工具来强化课堂上的概念，也可以使学生熟悉电子元件的特征方程。C-V表的仪表设计由DAC产生的电压源和加在被测设备上的电压阶跃源组成，C-V表测量的被测设备的电容通过RS-232串行通信存储到计算机中。C-V计为每个部分校准和测试，用于测量电容器和二极管的C-V特性。测量的结果是C-V的曲线表征。这些曲线与理论作了定性比较。

A simple and inexpensive C-V characterization system for electronics course at undergraduate level

A simple and inexpensive capacitance-voltage (C-V) meter based on C8051F006 SoC has been developed for characterizing electronic components. It can be a tool in laboratory to strengthen concepts delivered in lectures and also make students familiar with the characteristic equation of electronics components. The instrumentation design of C-V meter consist of a voltage source generated by DAC and voltage step source applied to device under test (DUT) and its capacitance, which is measured by C-V meter, are stored into computer via an RS-232 serial communication. The C-V meter calibrated for each part and tested for measuring C-V characteristics of capacitor and diodes. The result of the measurement is a curve characterization of C-V. The curves have been compared to the theory as qualitative.
