Physics Analog Electronics

PHYS  introduces the fundamental building blocks of analog electronic systems. The course begins with semiconductor physics, including atomic structure, materials, charge carriers, and the formation of P-type and N-type regions, leading to the PN junction. Students then explore diode operation, V–I characteristics, diode models, and rectifier circuits used in power supplies. Special-purpose diodes, such as Zener and varactor diodes, are studied for regulation and tuning applications. The course progresses to Bipolar Junction Transistors (BJTs), covering their structure, operation modes, characteristics, and use as amplifiers and switches. Students also learn DC biasing methods, including voltage-divider bias. The class concludes with Field-Effect Transistors (JFETs and MOSFETs), their characteristics, parameters, and biasing techniques, along with the introduction of IGBTs. Together, these topics provide a strong foundation for understanding and designing analog electronic circuits.
