Challenge Problems

Push your limits with challenges.

Question 1

A Common Source Amplifier has a threshold voltage of 1.5V and operates with a gate voltage of 3V. Calculate the required output voltage to keep the amplifier in saturation if the drain-source resistance is 500 ohms and you have an input signal of 0.1V.

💡 Hint: Use Ohm's law to relate the output voltage to the current flowing through the drain-source resistance.

Question 2

Design a biasing circuit for a Common Source Amplifier where the desired DC gate voltage is 5V and the output should provide a gain of 10. What values for the resistors would you need?

💡 Hint: Remember to apply the voltage divider concept along with the amplifier gain formula.
