Challenge Problems
Push your limits with challenges.
Question 1
Design a multi-transistor amplifier using active loads for a specified gain of 1500. Given transistors with β values of 120 and 80. Outline the steps you would take and the relationships you'd use to achieve this.
💡 Hint: Look at the relationships between components, and how each one affects the others.
Question 2
Given the output voltage swing of a CE amplifier using active load is 10V-2V, analyze how this range impacts the linearity of amplification. What are the expected consequences if the load capacitance increases?
💡 Hint: Understand how signal integrity is influenced by these factors.
