Challenge Problems
Push your limits with challenges.
Question 1
A common emitter amplifier with an active load is designed with specific NMOS and PMOS characteristics: NMOS with K' = 100 µA/V^2, and PMOS with K' = 50 µA/V^2. Calculate the expected gain if both devices are biased for equal current of 1 mA.
💡 Hint: Use the relationship between transconductance and biasing to solve this.
Question 2
Design a circuit that showcases both active and passive loads and predicts the gain between these configurations using specified component values.
💡 Hint: Think of what happens when you switch the type of load and analyze each phase.
