摘要

本文研究了微控制器集成电路电源对附近I/O引脚的传导发射。我们的研究表明，随着与电源对距离的增加，I/O引脚的传导发射减小。在集总电路模型中，可以用互感和互电容来描述从电源对传导发射到I/O引脚的扩散。

Conducted emission of I/O pins near power pairs of a microcontroller integrated circuit

In this paper, we investigate the conducted emission of I/O pins near power pairs of a microcontroller integrated circuit. Our investigation show that with the increase of the distance from the power pairs the I/O pin gives decreasing conducted emission. The spread of the conducted emission from power pairs to I/O pins can be depicted by mutual inductance and mutual capacitor in a lumped circuit model.
