EE 4152 - Low-Noise Electronic System Design2 lecture hours 2 lab hours 3 credits Course Description This course introduces the analysis and design of low-noise analog amplifiers. The different noise mechanism and models as applicable to analog electronics are introduced. Fundamental noise mechanism, amplifier noise models, noise in feedback amplifiers, noise in BJTs and FETs, and low-noise design methodologies for amplifiers and power supplies are covered. SPICE is used to analyze, model, and design various different projects.
