Common Source Amplifier MOSFET (LTspice)

In this video, I use LTspice to simulate a common source amplifier. Using an NMOS MOSFET, I explain the key equations needed to understand and set up appropriate resistance values for a desired gain. This is not a small signal model demonstration, however, the equations used are directly derived from a small signal model. This is a very simple example, I use a MOSFET that has no lambda value, therefore I assume that our r_o is infinite. This greatly simplifies our calculation for what R_D needs to be. Keep this in mind as you watch the video. 00:00 CS Amplifier Intro 00:48 LTspice Setup 03:33 Determining Unknowns 04:24 Finishing the Circuit
