Question

Generally the substrate terminal in an NMOS is tied to
​

Answer 1

Answer:

The substrate of PMOS should be connected to VDD and NMOS to GND in CMOS technology. for PMOS vgs<=vtp(which is -ve), so if source is connected to VDD, then vgs becomes Vg-Vs=-ve as VDD is always higher or equal to gate voltage. opposite is case with NMOS..
