Share:
- 1JFETs use a PN-junction for gating, while MOSFETs use a direct metal-semiconductor Schottky junction
- 2MOSFETs are unipolar devices while JFETs are bipolar devices
- 3The gate of a MOSFET is voltage-controlled and significant current flows through it under steady-state conditions
- 4The gate of a MOSFET is insulated from the channel, resulting in extremely low gate current compared to a JFET✓
Correct answer
The gate of a MOSFET is insulated from the channel, resulting in extremely low gate current compared to a JFET
