KNOWLEDGE AND UNDERSTANDING
Students acquire knowledge and understanding about the principle of operation of the main electronic devices (diodes, transistors) and of the laws regulating the operation of electronic circuits, starting from simpler ones (containing only resistors and capacitors) to more complex ones (e.g. amplifier circuits, digital circuits).
APPLYING KNOWLEDGE AND UNDERSTANDING
Such knowledge is applied in the resolution of electronic circuits with growing complexity, as are commonly encountered in the experimental practice.
After being trained on the solution of several examples, students use the acquired tools on similar yet more complex electronic systems. They are stimulated to develop critical sense and creative solutions and to increase their personal attitudes in problem solving.
Lectures contain frequent sessions of collective exercise solution, where the teacher stimulates the discussion among the students. Different approaches in problem solving are encouraged.
The course aims at providing the students with the tools to face problems of increasing complexity. This makes the students capable to expand the horizon of their knowledge following a well-indicated path.
Understanding of basic operation principles of electronic devices and their use in circuits. Development of creative skills in the design and simulation of circuits as can be encountered in many experimental problems and activities.
Electromagnetism as learned in a standard General Physics II course.
Resistance and capacitance as circuit elements. Signals.
2. Operational amplifiers.
Main characteristics and specifications. Internal structure of an opamp. Opamp circuits: differentiator, integrator, summer, voltage follower. Feedback and stability. The data sheet of a real opamp.
3. Basic electronic devices and their applications.
Diodes, MOS transistors. Basic diode and transistor circuits.
4. Analog to digital and digital to analog conversion.
Main characteristics and specifications. Examples of ADC and DAC circuits.
6. Introduction to digital electronics.
Numeric and alphanumeric codes (binary, octal, exadecimal). Boolean algebra. De Morgan’s theorems. Fundamental logic gates.
7. Combinatorial digital electronics.
Encoders and decoders. Multiplexers and demultiplexers. Adders and subtractors. Digital comparators. Parity checkers. What is a bus? Tri-state gates, open collettor gates and their use in a bus. Some examples of data transmission protocols in a bus.
8. Sequential digital electronics.
Flip-Flops (FF). Synchronous and asynchronous FFs. Registers, memories, counters. Disegn and simulation of a counter. Different memory archidectures: RAM, FIFO.
9. Some examples of complex digital systems.
DLL, PLL, communications interfaces, programmable logic circuits, microprocessors, data acquisition systems.
Frontal lectures, hands-on practising by means of simulation software tools (Spice/Verilog), practical and interactive demonstrations in the laboratory.
Verification of learning
1. Design and simulation of a digital interface, with detailed report on the work done.
2. Oral seminar and discussion on the report and on the main argument of the course.
Sedra-Smith “Microelectronic Circuits”. Horowitz-Hill “The Art of Electronics”. Masetti-D’Antone “Elettronica digitale”. Teacher’s slides and written documentation.
The course is held during 2nd semester. Students of both 2nd and 3rd year can attend.
