ECE 351C - Electronic Circuits (4 units)

Description: Covers operational amplifiers, diode circuits, circuit characteristics of bipolar and MOS transistors, MOS and bipolar digital circuits, and simulation software. Students will get experience with the fundamental nonlinear devices for circuit design: diodes and transistors. They will learn how to analyze simple linear amplifier circuits with these devices, use small signal models, and build digital logic gates.

Grading: Regular grades are awarded for this course: A B C D E
