Hi,
When I looked at the layouts of CMOS, I often found
pfets are surrounded by deep trenches. Is it required or not?
If I only use pfets for low frequency application, can I
ignore the deep trenches?
If I have high frequency signals around CMOS, I think it's
better to use a deep trench wall to enclose all the pfets and nfets.
Thus they will not be affected by the high frequency signals, am I right?
