Challenge Problems

Push your limits with challenges.

Question 1

Consider a CE amplifier with R = 1kΩ and C = 10µF. Derive the cutoff frequency and plot the Bode plot. What implications do these have for signal processing?

💡 Hint: Using R and C, derive RC time constants and relate them back to the overall performance.

Question 2

You're given a CS amplifier with a varying load capacitance of 50pF linked to a resistance. How does this load capacitor interact with the existing circuit to influence overall gain?

💡 Hint: Examine how load impacts gain calculations based on your earlier lessons on capacitive effects.
