Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A MOSFET has a threshold voltage of 0.4V. If VGS is 0.8V and VDS is 0.6V, determine the operation region and justify your answer. Also, describe how you would use this application in a circuit.

💡 Hint: Break down the volumes and use definitions to keep you grounded in the explanation.

Challenge 2 Hard

Design an application where the MOSFET operates in the triode region. Explain the configuration and output characteristics you expect.

💡 Hint: Think about feedback design principles to stabilize output.
