Course Content
Challenges associated with high-resolution data converters using Nyquist rate converters will be evaluated. Concepts on oversampling and its effect on the data converter circuit and the associated tradeoffs will be studied. Tradeoffs associated with process mismatch/ offset, area, and power, in the design of data converters and the concept of noise-shaping will be introduced. The use of noise-shaping in realising high-resolution analog to digital converters for audio, biomedical and RF applications will be modelled and simulated as part of assignments. Design of high-resolution digital-to-analog converters (DAC) using noise-shaping concepts and the advantages associated with a thermometer, segmented DAC and dynamic element matching will be detailed. Through the course project, students will be able to design a high-resolution ADC/DAC starting from system-level modelling to schematic simulations with mismatch.
