[amp_mcq option1=”Threshold voltage” option2=”Vss” option3=”Vdd” option4=”Vgs” correct=”option1″]
The correct answer is: A. Threshold voltage
The threshold voltage is the gate voltage at which a MOSFET starts to conduct. It is affected by the doping concentration and depth of the P-well. A higher doping concentration and a deeper P-well will result in a lower threshold voltage.
The other options are incorrect because:
- B. Vss is the source voltage. It is the voltage applied to the source terminal of a MOSFET. The source voltage does not affect the threshold voltage.
- C. Vdd is the drain voltage. It is the voltage applied to the drain terminal of a MOSFET. The drain voltage does not affect the threshold voltage.
- D. Vgs is the gate-source voltage. It is the voltage applied between the gate and source terminals of a MOSFET. The gate-source voltage affects the threshold voltage, but the doping concentration and depth of the P-well have a greater effect.
