Hello,
I leanred that the MOSFETs have symmetrical structures and thus source and drain are interchangeable and have drain current equations
@ saturation region
@ linear region
However, today I was told that power MOSFETs have different manufacturing process and have non-symmetrical shape which makes me to think that the source and drain are not inter-changeable.
Then, if an nFET is used as a low side switch of a buck converter, does same linear region equation apply?
Thanks,
