Programma dettagliato e risultati di apprendimento attesi

GOALS


The course SENSOR SYSTEMS will provide the basis for understanding how sensors work (CCD, temperature sensors, touch sensors, microphones, MEMS, etc.) and for designing analog and digital front-end circuits.

 

COURSE CONTENTS

 

1. ANALOG FRONT-END CIRCUITS


Operational Amplifier (OpAmp): ideal structure, open loop and negative feedback, non-idealities.
Stability of OpAmp circuits and frequency compensation techniques.
Linear circuits with OpAmps and analog filters, Instrumentation Amplifier (INA).
Non-linear circuits with OpAmps: Schmidt trigger, oscillator.
Basics on noise: spectral power, equivalent bandwidth, effective value, Signal-to-Noise Ratio.
Case studies on circuits with OpAmps and SPICE circuital simulations.


2. MIXED-SIGNAL ELECTRONICS


Sampling and Multiplexing: S&H circuits, static and dynamic errors, aliasing.
Digital-to-Analog Converters (DAC): architectures, precision and accuracy, conversion speed, trade-offs.
Analog-to-Digital Converters (ADC): architectures, timings, performance.
Under- and Over-sampling, Sigma-Delta modulator, noise-shaping and SNR.
Data Acquisition boards (DAQs): data-sheets, selection criteria.


3. SENSORS AND INDUSTRIAL APPLICATIONS


Basics on sensors: definitions, classifications and characteristics.
Working principle and front-end circuits of the most employed sensors: light and imaging (photodiode, CCD and CMOS sensor), temperature (RTD, thermistors, Thermocouple, diode, IR thermometer), magnetic field (Hall sensors, magneto-resistances), strain and forces (strain gauges, piezoelectric sensor), displacement, distance and proximity (capacitive, inductive, acoustic, optical, magnetic sensors, touch sensors), acceleration and orientation (MEMS), audio (dynamic and condenser microphones).
Hands-on examples of sensor interfacing with an ARM microcontroller.


4. CASE STUDY


Unmanned Aerial Vehicle (UAV, drone) sensor network.


Note Sulla Modalità di valutazione

Course assessment is based on an oral test (with analytical exercises and projects, covering the whole course contents). 

 

Different skills will be evaluated, and in particular:

- knowledge and understanding of the theoretical basics of sensors and readout circuits,

- ability to apply knowledge and understanding in practical examples

- communication skills

 

The same importance will be given to all the sections of the course, comprising the ability to interface sensors using a microcontroller.

 

The examination is passed if the overall mark is equal or higher than 18/30.
