Question
Consider an -channel metal oxide semiconductor field effect transistor (MOSFET) with a gate-to-source voltage of . Assume that , , the threshold voltage is , and the channel length modulation parameter is . In the saturation region, the drain conductance (in micro seimens) is ________
Correct answer
28 to 29
Solution
The drain current in the saturation region including channel length modulation is given by:The drain conductance is defined as the derivative of the drain current with respect to the drain-to-source voltage:Given the following parameters:

AI-powered practice· Unlimited practice on eligible plans
- PYQs with solutions
- Attempt available previous-year questions, then compare your reasoning with the worked solution. Coverage varies by stream.
- Practice that adapts
- Choose a topic, work on weaker areas and bookmark questions to revisit. Your attempts feed your progress tracking.
- AI doubt support
- Ask follow-up questions about a step or concept while practising, instead of stopping at the final answer.
