ELECTRONICS AND INSTRUMENTATION (UNIT INSTRUMENTATION)
Learning outcomes of the course unit
The course aims at providing insight into the operation of the building blocks most frequently encountered in the analogue signal conditioning chain in electronic instruments.
Fondamenti di Elettronica A, Fondamenti di Elettronica BC
Course contents summary
Analogue signal conditioning
The main functional blocks in a data acquisition and processing system.
A deeper insight of operational amplifiers. OTA and trans-impedance amplifiers. Electrometric amplifiers, instrumentation amplifiers, isolation amplifiers.
Log-antilog amplifiers. The Gilbert cell. Analogue multipliers and their application in true rms measurements.
Voltage and current references
Zener, Vbe, Vth and band-gap references. Implementations in bipolar and CMOS technologies.
Sample and hold circuits.
D/A and A/D converters.
D/A’s based on resistive weighting: binary weighting, block-binary weighting, direct and inverse R-2R networks.Capacitive weighting: binary weighting, serial conversion.
Complements on A/D converters:over-sampling converters, delta-sigma converters, high speed converters.
Phase Locked Loops
Phase detection, VCO, linear PLL analysis in the phase domain. Type and order of the PLL. Steady state errors and tracking characteristics.
Exercises Simple exercises are solved during the lectures. Homework.
There is a single examination covering the modules of Electronics and Instrumentation.
Evaluation: homework (1/4), experimental activity (1/4), oral examination (1/2)
