Aim

The goal of this course is to give the student a deep understanding of both theoretical and practical issues in the design of A/D and D/A converters, which are fundamental and ubiquitous functions at the interface between analog and digital circuits. In particular, we will focus on converters designed around Delta-Sigma modulators.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• •be able to describe the fundamental theory behind Delta-Sigma AD/DA converters
• •be able to describe the most important definitions and specifications in the design of Delta-Sigma AD/DA converters
• •be able to describe the various implementations of Delta-Sigma modulators, with main advantages and disadvantages
• •be able to describe the critical components and sub-blocks in Delta-Sigma modulators and their implementation in CMOS processes, as well as the limiting factor for modulators performance

Competences and Skills

For a passing grade the doctoral student must

• •be able to apply the knowledge acquired in the course to design a Delta-Sigma A/D or D/A converter suitable for a practical application
• •together with a fellow student, be able to simulate and layout the Delta-Sigma converter

Judgement and Approach

For a passing grade the doctoral student must

• be able to orally communicate the results obtained from the laboratory work
• be able to contribute sufficient fundamental concepts and knowledge so that a competent person in this area can document the idea, the problem and the solutions
