Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a Wien Bridge oscillator with specified component tolerances. How would component variations impact the final frequency?

💡 Hint: Consider how variations in resistance and capacitance will shift the frequency.

Challenge 2 Hard

Construct a detailed comparison chart of the efficiency and performance metrics of Wilson and Widlar current mirrors against the simple BJT current mirror.

💡 Hint: Use parameters such as output resistance and current matching accuracy to guide your comparisons.
