Hello,
I have an question about the ESD.
The picture I've attached is an ESD protection circuit for digital output.
I've used this pad but I wanna change the circled nMOS size of output inverter at this time because I need to drive more current than before.
The problem I've encountered is this: increasing W or decreasing L.
Which method is the best?
Decresing the size of L is an easy answer but I'm worrying that it may be damaged by ESD.
I think, of course, there's no matter whether I changed it or not if the esd protection circuit on the pad is properly designed.
But I'm still concerned about it.
Please share your experience and opinion.
Thanks!
