Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total gain from cascading two amplifiers with gains of 15 and 10, if the loading effect drops the effective gain by half.
💡 Hint: Consider how the loading effect changes your expectations about gains.
Question 2
Given a CS amplifier with a cutoff frequency of 2 kHz and a CE amplifier with 1.5 kHz, determine the overall upper cutoff frequency after cascading.
💡 Hint: Think about which stage limits the upper frequency response.
