In this video, I explain how to get the MOSFET threshold voltage from the MOSFET band diagram under applied bias, and I describe a couple of the subtleties involved that often trip people up when trying to calculate it.
This is part of my series on semiconductor physics (often called Electronics 1 at university). This is based on the book Semiconductor Physics and Devices by Donald Neamen, as well as the EECS 170A/174 courses taught at UC Irvine.
Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
