Challenge Problems
Push your limits with advanced challenges
Design a scenario in which you need to cascade two common emitter amplifiers; what challenges might arise, and how would you use buffers to solve them?
💡 Hint: Consider each amplifier's specifications when discussing potential gains and bandwidth.
Consider a circuit with a CE amplifier with gain A1 = 10, cascaded with another CE amplifier with gain A2 = 5, experiencing 30% loss due to loading effects. Calculate the effective gain.
💡 Hint: Remember to apply the loss factor after calculating the initial product gain.
