Presentation
The course is designed to allow students to gain pratical experience in circuit and system design as well as theoretical insight into principles of data-conversion and signal processing systems. The course extensively relies on practical labs to illustrate theoretical aspects with focus on audio applications.
Course content is structured around three major topics :
1. Delta-Sigma Analog-Digital Converters
In this part, fundamental theory of data converters is recalled. The focus is then on the delta-sigma type analog-to-digital. The theory is supported by simulation exercises with MATLAB. A complete data converter architecture is implemented with programmable analog and digital circuits.
2. Digital-to-Analog conversion
This part is covered by a half day practical exercise aiming at the implementation of a delta-sigma digital-to-analog converter in a Field Programmable Gate Array (FPGA).
3. Switched amplifiers for audio applications
A half-day lecture introduces the design of switched-mode audio amplifiers in Integrated circuits (ICs), i.ex. for applications such as portable audio or wireless communication terminals. Another half-day is spent on the design and measurement of such an amplifier implemented by means of programmable circuits.
