output driver
(Also posted in the analog ic design forum, sorry for the spam)
There is a general configuration of esd protection.
My question is: with Rs protecting the output driver, the output frequency is also limited by it. Can I just remove the Rs resistor for BW purpose?
I've read several documents and some of them just protect the output driver with the double diode as primary esd protection (no Rs). On the other hand, during an esd event, especially the CDM event, the node voltage at the pad (Vpad) could be greater than 10V. It seems that even using stacked transistors won't protect the output driver adequately.
Please feel free to tell me your opinions.
Thanks in advance.
