| 摘 要： | 针对传统Sawyer-Tower电路测量薄膜电滞回线的不足，提出了电荷积分改进方案。并在改进Sawyer-Tower电路基础上,结合虚拟仪器测量思想，组建以Lab VIEW和NI公司数据采集卡为核心的软硬件平台测量系统，并结合Matlab对采集数据进行分析处理，实现薄膜本征电滞回线的精确测量。经实验验证本测试系统可以快速准确完成薄膜电滞回线测量。

| Abstract: | Due to the shortcoming of measuring method of the ferroelectric hysteresis loops based on the traditional Sawyer-Tower Circuit, a method is proposed to improve Sawyer-Tower Circuit by charge integration in measuring hysteresis loop of ferroelectric thin film. The measurement system is realized with the application of LabVIEW and NI PCI_ 6221. According to the defect of LahVIEW in complex numerical analysis and processing, the mixed program between LabVIEW and Matlab is designed in the system. The results show that this system is very efficient. |
