not 3 port ,it is 3 node/terminal element if we neglect body terminal.You know.

Thanks again 💪

Thank you Sir 👍 Very helpful and very Simple conpect! Case 1: CLM=0 gmvgs=vo/Rs,-gmvo=vo/Rs，vo(1/Rs+gm)=0..Answer Case 2: CLM is not equal to 0 (vin-vo/ro)=(vo/Rs)+gmvo, vin/ro=vo(1/ro+1/rs+gm), vo/vi= 1/[ro*(1/ro+1/Rs+gm)]....Answer

The Significance of this circuit can be understood to analyze power supply rejection of a source follower circuit or to analyze a power supply rejection of an LDO (assuming we have an Opamp in feedback)

Exactly,for high Psrr we can use this pass MOSFET for a LDO
