Explore the fundamental principles and advanced concepts of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) through this comprehensive course from Purdue University's Electrical and Computer Engineering department. Master the essential physics underlying MOSFET operation, starting with transistor fundamentals, compact models, and circuit applications in both digital and analog/RF systems. Delve into energy band diagrams, MOSFET I-V theory, and the square law governing device behavior while learning the virtual source model approach. Study MOS electrostatics using energy band diagram methods and the depletion approximation to understand gate voltage effects, surface potential relationships, and mobile charge characteristics. Examine transmission theory through the Landauer approach for both low and high bias conditions, analyzing ballistic MOSFETs and velocity considerations at the virtual source. Investigate advanced topics including MOSFET scaling limits, power MOSFETs, High Electron Mobility Transistors (HEMTs), PN junction reviews, Heterostructure Bipolar Transistors (HBTs), and compact model circuit analysis. Gain practical insights through experimental analysis and develop a thorough understanding of device metrics essential for modern semiconductor device engineering and circuit design applications.
