CMOS集成电路电流参数测试分析

CMOS integrated circuit current parameter analysis

基于在工作过程中遇到部分CMOS集成电路性能不稳定等原因,通过多次试验,发现CMOS集成电路的输入电流(Ii)、电源电流(Icc)对电路的整体性能影响较大,本文对输入电流和电源电流的定义、测试原理、测试必要性、影响测试结果准确性因素等几个方面进行了理论方面的叙述。最后采用54HC14集成电路进行了实际测试试验,得出本文里所使用的电流测试方式是准确可行的。

The part of CMOS integrated circuit performance is not stable in the working process. So it found the CMOS integrated circuit of input current （Ii）, the power supply current （Icc） impact on the performance of the overall circuit through many experiments. In this paper, it has carried on the theoretical aspects of the narrative that the input current and electric current, testing principle, testing the necessity, the definition of factors influencing the accuracy of test results and so on. 54HC14 is used for the actual test experiment. It is concluded that the method of the current test in this article use is accurate and feasible.
