Course Objectives

The course provides a broad survey of analog and digital electronics, with particular focus on the issues relevant to electronic measurement systems in industry. The aim is to familiarise students with the devices and techniques commonly used in electronic instrumentation. The main topics are microelectronic technologies and devices, operational amplifiers (linear and non-linear analog signal processing), analog-to-digital converters, CMOS digital systems (from basic logic gates to complex systems such as RAM and ROM memories).

Course Prerequisites

Basic electromagnetism

Teaching Methods

Classroom lectures

Assessment Methods

Written exam at the end of the course. The exam requires that students provide the solution to two exercises about electronic circuits, and answer three questions about the subjects discussed during the course.
