G6A09
Which of the following describes MOSFET construction?
Pick an answer to check it.
Answer: B. The gate is separated from the channel by a thin insulating layer
In a MOSFET (metal oxide semiconductor FET), the gate is separated from the channel by a thin insulating oxide layer. That insulation gives it a very high input impedance.
Tip: MOSFET gate is insulated by oxide.
