MOSFET Dynamic Behavior Quiz

What is MOSFET switching behavior?

• Slowly switching between on and off states

• Staying in the same state regardless of the input signal

• Switching randomly without any pattern

• Rapidly switching between on and off states in response to an input signal

Explain the concept of threshold voltage in MOSFET switching behavior.

• Maximum voltage required to turn on a MOSFET

• The voltage at which a MOSFET stops conducting

• It affects the capacitance and charge/discharge time of the MOSFET.

• It has no effect on the switching speed

• It increases the resistance of the MOSFET

• It causes the MOSFET to overheat
