Hi,
I am new to analog layout. I have a PMOS diffamp with its Body shorted to source. So how should I draw the guard ring around it. Is the way I have drawn correct? Can I remove the 2nd Well ring? Is there any other method? Also please explain difference ( if any ) between n/p tap and n/p guard ring (well guard ring) ?
What should be the spacing between the contacts (metal) on the rings?
Thanks.
