vivek rajput said:In mixed signal ckts there is only an imaginary line to seperate the Digital and Analog parts.The SUB is common for both ,digital ckts usually operate at higher frequencies so thet switch on and off at very faster rate.They dump minority charge carriers in the SUB which can affect the analog nmos's behaviour.so there is a need to protect analog nMos transistors form this sub noise so there is a concept of Deep N Wells.Plz check the attachment to get the exact picture of Deep N Well..this is not the case with pMOS because we draw p MOS transistors in n Well
