基于RISC-SOC微电容测量模块的研制

Development of Micro-capacitance Measuring Module based on RISC-SOC

采用一片集成的RISC-SOC混合信号处理器产生高稳定度的正弦波,做电容测量电路的激励源,对测量结果进行ADC采样,并采取措施抑制引线电容和屏蔽外部干扰,得到高精度的电容测量值。

A RISC-SOC mixed-signal processor is used to generate a high stable sine signal as a signal generator of measuring circuit,and sample measuring result,and measures are taken to restrain down-lead capacitance and suppress interference.then we get high-accuracy capacitance measurement data.
