Goals:	Creational Structure:  Students will understand elementary semiconductor device physics at the level of equations which model the terminal characteristics of diodes and transistors.  This means that students will be able to represent a diode or transistor circuit via a well labeled schematic drawing, derive appropriate equations from the schematic, and know how to solve those equations.  Students will be able to carry out these analyses in the frequency domain when appropriate.
Creational Development:  Students will be able to apply several design techniques for stabilizing bias levels.  They will understand tradeoffs involved in choosing a bias technique. Students will be able to design circuits involving one or two transistors used in well-known configurations such as a current mirror, cascode amplifier, feedback amplifier, etc.  They will understand a historical perspective of how these techniques have improved over time.  This will be the main goal of this course.
