Challenge Problems
Push your limits with challenges.
Question 1
Design a current mirror where the reference current is 2 mA and the output is affected by Ξ» = 0.02 V^-1. Find the output current for V_ds = 6V.
π‘ Hint: Don't forget to factor in the finite lambda when computing current to maintain accuracy.
Question 2
Assess a current mirror design using MOSFETs with different K values. Derive how altering one K value affects the overall performance.
π‘ Hint: Compare before and after values and examine the changes thoroughly.
