The MOS transistor (MOSFET) is the workhorse of the microelectronic revolution. It is estimated that there are currently over 1 billion transistors per human being in the world. Part of the MOS transistor's success lies in its very small size (you can fit 1,000 of them within the width of a human hair!), part lies on some amazing things this device can do. However, the descriptions of MOS transistors in basic electronics courses cannot begin to do justice to this device. If you want to really know how the MOSFET operates, and how to model it, you need to study it carefully and systematically. This course will help you do just that.
The course starts with a review of basic physical principles, and expands into a detailed treatment of MOS transistor phenomena, in a logical and systematic fashion, enhanced by intuitive discussions. We discuss a hierarchy of models - from the simple to the sophisticated - clearly identifying the connections between them, and encompassing many aspects of modeling, including dc, large-signal transient operation, quasi-static operation, non-quasi-static operation, small-signal operation, noise, and structural effects. We discuss the concepts on which the most popular CAD (computer-aided design) MOS transistor models are based.
