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.
π‘ 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 2kΞ© and the input resistance of the second is 3kΞ©, calculate the net gain including attenuation.
π‘ Hint: Break it down to verify each part of the calculation.
