Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier's passive load configuration, calculate the expected voltage gain and then redesign it with an active load approach to improve gain by at least 50%. Show the calculations.
💡 Hint: Use the formula for voltage gain but consider the variable nature of the active load.
Question 2
Discuss in detail how changing one parameter in a common emitter amplifier configuration can vastly alter its performance. Provide examples.
💡 Hint: Think about the operational characteristics and their relationships.
