Basic knowledge of Electron Devices (MOS) and Circuit Theory
Introduction to electronic systems
Basic design concepts (analog vs. digital)

Lectures (70h) and lab sessions (30h). Lectures are interactive and meant to stimulate the students to propose solutions and ideas.
Verification of learning
Written exam (4 exercises)and discussion. The final grade is the average.
Students who attend the lectures will have the opportunity to partition the exam in 2 written partial exams that will take place according to the faculty calendar. Final grade is the average of the grades obtained in the 2 partial exams.
The main aim of the written exam is to verify the acquired skills in terms of circuit analysis and design.
Analysis: the student will be asked to analyze a circuit and identify some figures of merit; as an example, given a logic gate determine propagation delay or power consumption.
Design: given a set of specs, the student will be asked to choose the proper circuit topology and size the components such as transistors, capacitors and resistors; as an example, given bandwidth, power consumption and gain, sizing all the device of an OTA.
The oral exam has the aim to verify the skills in terms of circuit theory and design techniques and to verify if the capability to solve the exercises derives from a deep comprehension of the design methodology.
