Hi
I know from my circuit theory lecture.NMOS bulk is connected to ground/source terminal/most -ve voltage in ICs and in PMOS the bulk is connected to VDD/source terminal/most +ve voltage in ICs. However in FDSOI technology bulk/body can be connected to some DC voltage. I would like to know in NMOS when to connect it to ground and to some DC voltage ,advantages and disadvantages of both ways
Bulk driven MOS is used for low voltage operations. It removes the threshold voltage from the signal path because signal is applied at bulk. Secondly it helps in linearity improvement as it inherently attenuates the signal.
But it increases the input referred noise. Chip area, parasitic capacitance increases.
