Question 1
What does Gain Margin (GM) indicate?
- A measurement of phase lag
- A measure of stability before oscillation
- The overall bandwidth of a system
💡 Hint: Focus on the definition of GM.
Question 2
True or False: A Phase Margin (PM) above 60 degrees may indicate a sluggish response.
- True
- False
💡 Hint: Think about the relationship between PM and system response.

Question 1
A feedback amplifier has a phase crossover frequency of 3 kHz, and the loop gain at this frequency is measured at -9 dB. What is the Gain Margin, and what implications does this have for the design?
💡 Hint: Apply the GM formula.
Question 2
Given a PM of 25 degrees in an amplifier design, outline the steps to increase this margin to an acceptable level, suggesting specific components or techniques that might be employed.
💡 Hint: Reflect on how feedback affects phase.
