Training objectives
- The course, which provides 6 CFU credits (42 hours), aims to offering students the opportunity to understand the principles of operation of the main semiconductor devices employed in microelectronic systems for data acquisition and processing and to study application examples . Students are offered opportunities, especially during the lab sessions, to hone their skills in applying the knowledge gained.
Prerequisites
- The student should have acquired the basic knowledge provided by the courses of Physics and by the Electronics laboratories offered in the first two years of this Degree course.
Course programme
- The topics covered by the course are:
Introduction to silicon (Si) planar technology for the manufacturing of integrated circuits
Basic knowledge of crystallography and notions of quantum mechanics at the base of the understanding of the energy structure and the density of states for charge carriers in Si; Fermi function and concentration of charge carriers at thermal equilibrium; generation and recombination of carriers in Si; charge transport phenomena in semiconductors
Theory of the p-n junction at equilibrium and under reverse and direct bias; Schottky junctions; comparison between ideal and real I-V characteristics; junction breakdown; charge control model of the p-n junction and turn-off, turn-on transients
Applications of rectifier, Varicap and Zener diodes
SiPM (Silicon Photo Multiplier) devices for single photon detections
Theory and application of bipolar junction transistors (BJT); Ebers – Moll model; small-signal equivalent model; Bode diagram of the frequency response of single stage amplifiers; design of a simple operational amplifier in bipolar technology
Theory and application of field effect transistors (MOSFETs); Sichman - Hodges model; small-signal equivalent model; Bode diagram of the frequency response of single stage common-source amplifiers; design of a simple operational amplifier in CMOS technology
CMOS inverter; CMOS driver for large capacitive loads; CMOS combinatorial and sequential logic elements; power-delay product
Analogic applications laboratory: SPICE simulation of circuits examples seen in class
Digital applications laboratory: automatic synthesis of digital circuits described in hardware description language ( HDL ) and exercises based on development tools for FPGA ( Field Programmable Gate Array ) integrated circuits Didactic methods
- lectures, exercises of design and simulation of analog circuits, development of digital projects for FPGA integrated circuits
Learning assessment procedures
- The student is evaluated with an oral examination foreseeing:
• discussion of a topic chosen by the student or presentation of a report on one of the exercises of project or analysis seen during the course
• answering 2 questions proposed by the Committee which may include the analysis of the operation of a device inserted in a circuit of the type of those seen during the course
and having the purpose of verifying the knowledge and the skills acquired. The final grade is the weighted average of the evaluations of the responses Reference texts
