Challenge Problems
Push your limits with challenges.
Question 1
Design a common source amplifier that operates effectively with an input signal of 1V peak-to-peak. Assume you have a supply of 12V and a target gain of 10. What are the resistor values you should use?
💡 Hint: Break the problem into steps focusing on DC point, then gain.
Question 2
Consider a circuit with a MOSFET rated at 0.7mA/V for transconductance. If you wanted to redesign for an output swing of 4V around a midpoint of 6V using supply voltage of 12V, what should the new resistor values be?
💡 Hint: Remember to ensure the output voltage stays within the supply limits.
