ENGLISH VERSION
Learning Objectives
The course of Electronics for Telecommunications deals with architectural and circuital solutions of the radio frequency (RF) front-ends for the wireless communication systems, which are based on modern integration silicon VLSI technologies. The course aims at providing the knowledge of the main RF front-end architectures and of the electronic techniques for the most critical aspects of the RF processing, which are the high frequency, the high gain, the low noise and the high linearity.
At the end of the course, the student will acquire the knowledge of how a modern transceiver for the most widespread wireless telecommunication applications, such as mobile handsets, WLAN, WSN, Bluetooth, etc., is made, how it works, and how it is interfaced with the antenna on one side and with sensing and actuators on the other. Moreover, the student will be introduced to the design of the main RF processing building blocks (LNA, oscillator, PLL, etc.) thanks to the acquisition of the topologies of those circuits and their relative design equations.
Course Structure
The course is mainly based on lectures that will be recorded in both audio and written form and made available for students in the same day. Visits to research labs could be organized where typical design and measurement work flows will be shown. If the course is carried out with the distance learning or mixed approach, some variations could be made with respect to the previous declaration in order to meet the program described in the syllabus.
