Question

How do you bias P-channel Mosfet?

Answer 1

So for n-type enhancement type MOSFETs, a positive gate voltage turns \u201cON\u201d the transistor and with zero gate voltage, the transistor will be \u201cOFF\u201d. For a p-channel enhancement type MOSFET, a negative gate voltage will turn \u201cON\u201d the transistor and with zero gate voltage, the transistor will be \u201cOFF\u201d.
