Subject Overview:


Upon completion of this class, students will be able to design an analog-digital interface from system-level specifications such as input signal and disturbance characteristics. The students will learn how to design, analyse and characterise all components of an acquisition chain, including filters and A/D or D/A converters.


Principles of analog-to-digital interfaces: concepts of aggressors, noise, signal-to-noise ratio, dynamic range, resolution and accuracy. Methodology for interface design from system specifications. Filter architectures and implementations: Biquad and Ladder filters, switched capacitor and continuous-time filter; OTA-RC and opamp-RC implementation. D/A converter architectures and characterization: differential and integral non-linearity and spectral metrics; binary, thermometer and segmented architectures. A/D converter architectures: Flash, pipelined, successive approximation, oversampling converter. Analysis of error sources in A/D converter architectures and impact on design.

Learning Outcomes:


Having completed this unit the student should be able to:

  1. Determine the specification of critical blocks of an analog-digital interface from system/application requirements
  2. Characterize all components of an analog-digital interface (filters and A/D converters)
  3. Design and implement continuous-time and switched capacitor high-order filters
  4. Design and implement flash, pipeline, successive approximation or sigma-delta A/D converters

  • One written examination (not exceeding three hours) at the end of semester, worth 50%
  • 4-6 homework assignments each 250 words equivalent over the semester (approximately 25-30 hours of work per student), worth 20%
  • Design project, submitted project work of 1000 words per student, due at the end of semester (approximately 25-30 hours of work per student), worth 20%
  • Class Participation, worth 10%.

Intended Learning Outcomes (ILOs) 1-4 are assessed in the final exam, the submitted assignments, and class participation. ILOs 1, 3 and 4 are also assessed in the submitted project work.
