DEPARTMENT OF ELECTRICAL,COMPUTER AND BIOMEDICAL ENGINEERING
2nd semester (08/03/2021 - 14/06/2021)
23 lesson hours
Knowledge of basic electronic devices and circuits: operational amplifiers, diodes, FETs, MOS-FETs and their analog applications. This course represents the completion of the module Elettronica (Electronics) of the course Elettronica per Ingegneria Industriale (Electronics for Industrial Engineering), to which it specifically refers.
To complete the basic skills acquired by the module of electronics (‘Elettronica’) of the three-year Degree in Industrial Engineering, with the addition of topics such as: the BJT, feedback, power amplification stages, selected two-element active stages, the precision rectifier.
Complements on operational amplifiers
The super diode. The precision single and double half-wave rectifier. Logarithmic and antilogarithmic amplifiers. Current generators.
The BJT transistor
Physics of the BJT. Modes of operation. Polarization networks. Small signal circuit model. Basic single-stage BJT circuits. Multi-stage amplifiers. Cascode amplifier, Darlington amplifier, differential pair. The current mirror. Active loads. Applications.
Feedback in electronic amplifiers
Classification of feedback circuits. Stability. Effects of feedback. Examples of circuits with feedback.
Power amplification stages
Definition and classification of output stages for power amplifiers. Class A amplifiers. Class B and class AB amplifiers. Efficiency. Polarization circuits.
Photodetectors and applications.
The course includes classroom lessons where the theory of active elements and electronic circuits of the course is developed; classroom exercises where numerical examples are performed on analysis and synthesis of amplifiers and signal processing circuits with discrete elements and operational amplifiers
