Space and astronautical engineering

Introduction to analog and digital electronic signals. Shannon theorem. Sampling and quantization of continuous time signals. Representation of signals in the frequency domain. Frequency bands and related electronic applications. Electronic systems generalities. Bipolar components and linear two-ports networks. (1 CFU-ECTS) Definition and characteristics of electronic amplifiers: saturation, noise, and passbands. Single time constant (STC) circuits and their time response to canonic signals (step and pulse signals). Frequency response of STC circuits. Operational amplifiers (OP-AMP) and their main applications in inverting and non-inverting configurations. OP-AMP circuits: active filters, differentiators, integrators, summer, voltage-current converter. OP-AMP limitations: slew-rate, common-mode rejection, polarization currents, offset voltage. (2 CFU-ECTS) Electronic properties of semiconductors and charge transport mechanisms. Diffusion currents, drift current, carriers generation and recombination. Semiconductor junctions: non-biased and biased junction properties. Structure and working principle of diodes, bipolar junction transistors (BJT) and field effect transistors (MOSFET). Main diode circuits and their applications: half and full wave diode rectifiers. Zener Voltage stabilizer . Design of direct current supplier. Peak detector circuit. Analysis and comparison of single-stage BJT amplifiers: common emitter, common base, common collector. Analysis and and comparison of single-stage MOSFET amplifiers: common source, common gate, common drain. Current mirrors. Differential couples. (2 CFU-ECTS) Introduction to digital electronics. Laboratory experiences on diode and OP-AMP circuits. (1 CFU-ECTS)

Fundamentals of electrical circuits, electrostatics and electromagnetism from the courses of Physics of Laurea degree.

Sze, Dispositivi a semiconduttore, Hoepli on semiconductors and junctions working principle. S. Donati, Photodetectors, Prentice Hall for optical sensors A. d’Alessandro, Lecture slides can be downloaded from the website http://elearning2.uniroma1.it (registration is required) or through registration on classroom Lecture notes on all topics

Frontal Lectures, classroom exercises, review of homework assignments, laboratory experiences (only frontal)

Strongly suggested for a better understanding and grasp of the course topics.

The exam consists in both mandatory written and an optional oral test. Th written text consists in a numerical test of a bout two hours related to the design of simple basic electronic systems. Homework assignments are given and evaluated as 20% of the final grade. The oral test is on the theoretical concepts of the course and can contribute to a maximum of 10 % of the final evaluation.
