Challenge Problems
Push your limits with challenges.
Question 1
Given a common emitter amplifier with a transistor beta of 150 and Early voltage of 120 V, calculate the expected output voltage considering a baseline of 11.4V.
💡 Hint: Factor in current mirroring and compare with ideal voltage to find discrepancies.
Question 2
Design a scenario where mismatched beta values of 100 and 200 affect the output voltage of a current mirror setup, and analyze the outcomes.
💡 Hint: To visualize, sketch the current path and observably contrast both outputs to identify variations.
