Challenge Problems
Push your limits with challenges.
Question 1
If two common emitter amplifiers have gains of 12 and 8 with an input capacitance of 10nF for the second stage, calculate the overall gain assuming an attenuation of 0.5 due to loading.
💡 Hint: Use the product of gains and apply the attenuation factor.
Question 2
Discuss in detail how one might design an improved cascading system for amplifiers seeking to maintain bandwidth while maximizing gain.
💡 Hint: Consider the roles of input and output capacitance in your designs.
