To bias a e-MOSFET ___________(a) we can use either gate bias or a voltage divider bias circuit(b) we can use either gate bias or a self bias circuit(c) we can use either self bias or a voltage divider bias circuit(d) we can use any type of bias circuitThe question was asked in an interview.I'd like to ask this question from Biasing of JFET and MOSFET topic in division FET Amplifiers of Analog Circuits

Answer»

Correct OPTION is (a) we can use either gate bias or a voltage divider bias circuit

The best explanation: To bias an e-MOSFET, we cannot use a self bias circuit because the gate to source voltage for such a circuit is ZERO. Thus, no channel is formed and without the channel, the MOSFET doesn’t work properly. If self bias circuit is used, then D-MOSFET can be operated in depletion MODE.
