ECE 3204 Analog Electronics | ECE | Virginia Tech

Undergraduate PROGRAMS

Course Information


Small signal modeling of transistors. Basic architecture and functionality of linear amplifiers including transistor biasing circuits, current sources, differential amplifier, common emitter amplifier, common source amplifier, emitter follower, source follower, common base amplifier, and common gale amplifier. Frequency response of single stage and multistage amplifiers.

Why take this course?

This is an introductory course to analog circuits. The syllabus has been revised in coordination with ECE 4220 to provide a stronger foundation for students.

Required for all EE majors


2204 (grade of C- or better), 2704 (grade of C- or better), Co: 3274

This course requires 2204 Electronics and 2704 Signals and Systems as prerequisites and 3274 Electronics Circuits Lab II as co-requisite. A grade of C- or better is needed to make sure students have the required level of skills and background to take 3204. The material in 3204 is based on the properties of semiconductor devices taught in 2204 for electronic circuit design and analysis and requires the knowledge of Laplace transform as taught in 2y704 for frequency domain analysis. The content of this course is reinforced experimentally in 3274.
