Challenge Problems

Push your limits with challenges.

Question 1

You are given a CE amplifier with a gain of 18 and a bandwidth of 200 Hz. You cascade it with another CE amplifier with a gain of 10 but face a loading effect leading to a gain reduction by 0.5. What is the overall gain and how does the bandwidth change?

💡 Hint: Don’t forget to apply both concepts of gain and frequency response.

Question 2

Design a theoretical circuit with two cascaded CS amplifiers. The first has a gain of 15, and the second has a gain of 12, considering a loading effect of 0.7. How would you calculate the effective gain, and what factors would you identify that may affect the upper cutoff frequency?

💡 Hint: There's a combination of loading and capacitance you need to consider for cutoff frequency.
