Question
MOSFET has a thin layer of Silicon Oxide at the Gate terminal, which acts as
Select one:
a. Capacitor
b. Inductor
c. Semiconductor
d. Resistor
Solution
The thin layer of Silicon Oxide at the Gate terminal of a MOSFET acts as a. Capacitor.
Here's why:
-
The structure of a MOSFET includes a gate, source, and drain. The gate is separated from the body by a thin layer of silicon dioxide.
-
Silicon dioxide is an insulator. When voltage is applied to the gate, an electric field is created across this insulating layer.
-
This electric field influences the charge carriers in the body of the MOSFET, controlling the current flow from the source to the drain.
-
This behavior of storing energy in an electric field and releasing it is characteristic of a capacitor. Hence, the silicon dioxide layer acts as a capacitor.
