Type of Assessment
The standard exam is oral. It may be substituted by a written proof at the end of the Course. In both cases, the aim is verifying:
- by means of theoretical questions, the knowledge of main characteristics of circuits employed in digital systems;
- by means of exercises, the capability of designing simple digital systems and/or of evaluating the related properties.
- Boolean algebra, elementary logic gates (NOT, OR, AND,NOR, NAND), De Morgan Theorem and Karnaugh maps. Elementary sequential circuits (Flip-flop, transparent latch, registers)
- Elementary logic circuits: TTL and CMOS inverters. BiCMOS circuits.
- Integrated digital circuits
Package, available functionalities, main parameters (data sheet). State-of-the-art, low-voltage circuits. Input/Output volages and currents. Interconnection issues, noise margins.
Static and dynamic power consumption.
"Bus" issues: conflicts and "floating" buses.
Typical malfunctioning causes. Electrostatic discharge (ESD).
- Integrated digital circuits: timing issues of logic gates, buffer and bus-switch, latch, flip-flop D, register, counters (single or cascaded, programmable), read-only memories and RAM. Fundamentals of advanced integrated circuits (FPGA, DSP)
- A/D and D/A CONVERTERS. Generalities. Main architectures.
