About electronics Electronics is everywhere A field at the leading edge of technology, withrapid rate of progress Pushes the limits in speed, degree ofintegration, automation EE 331 Spring 2014Microelectronic Circuit Design UW EE Chen/Dunham
Where do we start? Materials Devices Circuits We already know about passive linearcomponents: resistors, capacitors, inductors We will learn about new nonlinearcomponents: diodes, field effect transistors We will use them to design and build circuitsEE 331 Spring 2014Microelectronic Circuit Design UW EE Chen/Dunham
After this course, you’ll be able to Calculate conduction properties of materials and simple devicestructures Explain the operating principles of semiconductor diodes and FETs Determine the in‐circuit operating state of diodes and FETs Perform large signal analysis of circuits containing diodes and FETs Use a modern schematic capture and computer‐aided circuitanalysis program (SPICE) Calculate the performance parameters for different MOS logicfamilies to design and build circuitsEE 331 Spring 2014Microelectronic Circuit Design UW EE Chen/Dunham
