Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total expected voltage gain in dB for a two-stage amplifier if the first stage has a gain of -30 and the second stage has a gain of -60.
💡 Hint: Use multiplication for total gain first, then convert to decibels.
Question 2
Design a two-stage amplifier given a target overall gain of 1000, choosing appropriate values for each stage gain. What might you pick for the coupling capacitors in this context?
💡 Hint: Start with the desired gains and break down into segments that combine multiplicatively to meet your goal.
