Challenge Problems
Push your limits with challenges.
Question 1
Analyze an amplifier that combines a CE stage followed by CC. If the initial gain is 250 and the CC addition reduces it by 10% while dramatically increasing bandwidth from 500 kHz to 10 MHz, discuss the overall impact on signal processing.
💡 Hint: Consider how trade-offs affect function.
Question 2
Given the original cutoff frequency of a CE amplifier is 513 kHz, and adding a CC stage brings it to 10 MHz, calculate the factor of increase in bandwidth and discuss its significance.
💡 Hint: Think of the frequency as a range that can be expanded.
