The effective channel length of a MOSFET in a saturation decreases with increase in___________?
Correct answer: B. Drain voltage
- A. Gate voltage
- B. Drain voltage
- C. Source voltage
- D. Body voltage
Explanation
Increasing drain voltage enlarges the drain depletion region, causing channel-length modulation and shortening the effective channel length in saturation. This produces a finite output conductance.
