摘要

TVS夹钳的一个非常重要的问题是它们能够将电压限制在可能损坏最先进的SOC I/O状态的水平以下，这可能在低至3.5V的电压下失效。由于将TVS的分流电阻降低到可接受的水平是非常困难的，另一种选择是在TVS和I/O之间引入衰减电阻。本文将研究饱和电阻作为保护低电平I/ o的一种手段。同时，建立了I/ o故障模型

Saturation Attenuator for TVS Devices

One very important issue with TVS clamps is their ability to limit the voltage below the level that can damage a state of the art SOC I/O which can fail at voltages as low as 3.5V. Since lowering the shunt resistance of the TVS to acceptable levels is very difficult, another option is to introduce an attenuation resistor between the TVS and I/O. This paper will look at the saturation resistor as a means to protect low level I/Os. Also, failure models of I/Os with be developed
