Specific course objectives

The course covers the fundamentals of the analysis of analog and digital electronic circuits. The course provides an overview of the working principle and physical models of the most important electronic and microelectronic devices, in particular diodes and MOS transistors, and of the operation of the most widespread functional blocks, such as operational amplifiers, signal conditioning circuits, A/D and D/A converters, NOT, NOR and NAND logical gates, flip-flops and memories. The course aims at developing the student skills in the analysis of op-amp based electronic circuits performing linear and non-linear signal processing (amplification, sum, subtraction, integration, differentiation, filtering, pulse generation), basic amplifying circuits including MOS transistors and simple digital circuits based on elementary combinatorial and sequential logic gates. It also aims at providing the student with the ability of choosing A/D and D/A converters complying with specific applications in industrial measurement systems. Beside the class lectures, the course includes laboratory activities on electronic circuit simulation, on the design and practical assembly of simple data acquisition systems and on the simulation and modeling of control systems.
