Challenge Problems
Push your limits with challenges.
Question 1
A given op-amp design has a unity gain bandwidth of 1 MHz and uses a compensation capacitor effectively causing a roll-off. Calculate the phase margin if three poles interact at high frequency.
💡 Hint: Count the total contributions of phase shifts from poles and how they affect unity gain.
Question 2
Design an op-amp circuit that involved dominant pole compensation. Indicate the placement of components and discuss the expected effects on bandwidth and stability.
💡 Hint: Think about how other components would influence overall behavior.
