| Summary | This course will equip the student with an understanding of sigma-delta data converters at a practical circuit level. The coursework makes a link between the digital signal processing concepts of sigma delta conversion and implementation in integrated circuit hardware.
Saturation, stability and limit cycle behaviour of modulator loops will be described and related to circuit structure. Non-ideal behaviour of modulators such as noise, matching, finite gain and settling will be related to circuit level implementations.
The course will be illustrated throughout with MATLAB, Simulink and Cadence examples linking to laboratory sessions and a design exercise issued at the start of the course. |

Learning Outcomes
On completion of this course, the student will be able to:
- Predict non-ideal circuit behaviour of modulators with SIMULINK and MATLAB;
- Use Cadence Design Systems software to study non-ideal effects in switched-capacitor modulator implementations;
- Propose circuit implementations of modulators and choose circuit component values to optimise performance.
