Hello,
Is there any way to separate grounds in an analog IC.
I made gnd_x ( ; x = the block number) pin for each block in the circuit but since these grounds are connected to the guard rings of nmos s and that nmoses are built directly in the substrate, I get shorts involving these ground nets in the LVS !
In the cmos p-process that I am using, I don't have a p-well layer to isolate these nmoses! How could I solve this issue?
Thanks,
