ELEC3208 Analogue and Mixed Signal Electronics

Module Overview

To cover in some depth those areas of circuitry likely to be used between an analogue signal source and a digital signal processing system, making maximum use of available integrated circuits. This fits in with our overall programme of providing a broad based electronics engineering course, with this module covering the main aspects of measuring outputs from a variety of sensors, designing interface circuits and amplifiers, filtering, and data conversion. The course will also cover important topics such as clock generation, noise management, power supply design, as well as practical issues such as packaging, EMC and PCB design. The issues are illustrated by case studies where applicable. It is assumed that the students at least understand the basics of opamp circuits, and basic analogue to digital conversion principles. ELEC2216 Advanced Electronic Systems is a required prerequisite as we build on and extend many of the concepts in this module.
