Challenge Problems
Push your limits with advanced challenges
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.
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.
