Obiettivi dell'insegnamento

The course SENSOR SYSTEMS will provide the basis for understanding how sensors work (image sensors, temperature sensors, touch sensors, microphones, MEMS, etc.) and for designing analog and digital front-end circuits. Through the course students will become familiar with sensors and electronic components data-sheets and also with different tools to simulate analog circuits and to program and debug ARM microcontrollers. The goal of the course is to enable master degree students to select the best sensor for a specific application, develop an optimized front-end circuit and acquire the output signal with a microcontroller.
