Challenge Problems
Push your limits with challenges.
Question 1
Design a two-stage amplifier with specified gains but ensure the cascaded gain meets target specifications despite loading effects. Calculate required buffer characteristics.
💡 Hint: Apply attenuation equations carefully.
Question 2
If the first amplifier has a gain of 12 and the second has 8, while the output resistance of the first is 2kΩ and the input resistance of the second is 3kΩ, calculate the net gain including attenuation.
💡 Hint: Break it down to verify each part of the calculation.
