Challenge Problems
Push your limits with challenges.
Question 1
A compound amplifier system consists of a CS amplifier with a 6 dB gain followed by a CD stage. If the CD stage has an input resistance of 10 kΞ©, how would you calculate the output resistance and overall bandwidth?
π‘ Hint: Reflect on how each stage affects output and perform series-parallel resistance calculations.
Question 2
Given a common source amplifier with a load capacitance of 100 pF and an output resistance of 3 kΞ©, derive the upper cut-off frequency. Determine how the frequency shifts when a CD stage is added.
π‘ Hint: Understanding the impact of C and R changes in series and parallel configurations is key.
