Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier with mid-band gain of 20 dB, calculate the power gain and explain the significance of this gain in circuit design.
💡 Hint: Consider the relationship between voltage gain and power gain.
Question 2
Analyze a scenario where you replace a coupling capacitor in an amplifier with a significantly smaller value. Describe the expected impact on f_L, gain at low frequencies, and overall frequency response.
💡 Hint: Think about how capacitance affects the time constant and therefore the cutoff frequency.
