Challenge Problems

Push your limits with challenges.

Question 1

A designer is working on a circuit with a desired output resistance of 50 kΩ. If λ for their MOSFET is 0.02 V⁻¹, what I_D must they design for?

💡 Hint: Rearrange the formula carefully to isolate I_D.

Question 2

Consider two MOSFETs with different λ values (0.04 V⁻¹ and 0.01 V⁻¹) but the same I_D (5 mA). Which will have a higher output resistance and why?

💡 Hint: Compare how changes in λ influence the calculation for r_o.
