Development of Calibration Device for Signal Processing Modules of EIS System
摘要
Abstract
Objective To research and design a calibration device for the signal processing modules of EIS system. Methods High-precision resistor was used to set the standard reference source so as to analyze the difference between measured impedance value and the reference resistor value, then the correction parameters of impedance magnitude and phase for each frequency were obtained. Results The accuracy and homogeneity of the EIS system could be improved by 15% and 18% at best respectively after calibration between 100-200 kHz. Conclusion The accuracy and sensitivity of EIS system can be improved by using the calibration device.关键词
