Question 1

Design an amplifier circuit with the specified requirements: Input voltage range of 1-5V and a gain of -10 using a MOSFET. What values would you choose for R_D and transconductance?

💡 Hint: Balance the resistor values with the operational characteristics of the MOSFET.

Question 2

If a MOSFET begins to clip at output voltages when fed a signal, what adjustments can be made to avoid distortion within the linear range?

💡 Hint: Consider the overall behavior of the circuit as components interact.
