Design: A Simple Common-Source Amplifier

• Instructions: This activity is structured as a tutorial with an activity at the end. Should you have any questions, clarifications, or issues, please contact your instructor as soon as possible.
• At the end of this activity, the student should be able to:

1. Design a simple common-source amplifier.

Activity 1: Transistor Intrinsic Gain

For a certain DC drain current, $I_{DC}$, and DC drain-to-source voltage, $V_{DS}$, we can determine the intrinsic NMOS small-signal gain, $a_{0}=g_{m}\cdot r_{o}$.
