This course covers the following: semiconductor and diode, small signal model of bipolar junction transistor (BJT), applications of BJT amplifiers, field-effect transistors, OP Amp and its applications to amplifiers and logic circuits, differential and multistage amplifiers, feedback and stability, integrated circuits, small-signal analysis, and tuned circuit. And The lab entails hands-on experiments with diode circuits and BJT small-signal low-frequency amplifiers. MOSFET devices and their application using small-signal amplifiers are discussed. Also, this course features the construction of logic gates using discrete devices, thereby understanding the characteristics of each logic circuit as well as an overview of analog and digital circuit theory.
