The controlling electrical parameter in a MOSFET is:
Multiple Choice Options
- A
VDS
- B✓ Correct Option
VGS
- C
IG
- D
IS
Detailed Technical Solution & Explanation
A MOSFET is a voltage-controlled device where the gate-to-source voltage () controls the electric field across the gate oxide, establishing the inversion layer channel and modulating drain current ().
Option Analysis:
•
Option A (VDS): Incorrect. Controls drain-source field but does not control channel induction.
•
Option B (VGS): Correct. Gate-source voltage is the controlling parameter.
•
Option C (IG): Incorrect. Gate current is essentially zero.
•
Option D (IS): Incorrect.
