Objectives
The goal of this course is to explain the basic electronic components, such as diodes and transistors. It is required that students learn the electrical characteristics of these components, as well as knowing to implement simple electronic circuits, based on several types of transistors and diodes.
Prerequisites
Knowledge of mathematics, electromagnetism and analysis of electrical circuits.
Subject matter
- Bipolar junction diodes. The ideal diode. Diode current-voltage characteristic. Circuit analysis with diodes. Small signals diode model. Zener diode. Rectifier circuits.
- Bipolar junction transistors (BJT). Transistor operation modes and characteristics. Polarization. Small signal models. Transistor amplifier circuits. The common-emitter. The common-base. The common-collector. Differential pairs. Current sources. Multi-stage amplifiers.
- Field effect transistors (MOSFET and JFET). Current-voltage characteristics. Biasing. Small signal models. Amplifier circuits.
- Basic logic circuits. Gates NAND, NOR and NOT using MOS transistors.
- The ideal operational amplifier. Circuit analysis with operational amplifiers. Non-ideal characteristics of operational amplifiers.

Teaching method
Theoretical and practical aspects of the subject are taught, along with the resolution of some exercises and examples. Students are randomly required to present the solution to the proposed problems, in the practical classes. Students are also required to implement the circuit calculations pertained to each laboratory session, before that session. A laboratory final project is elaborated.
