Analog-to-Digital Converters

(ADCs) provide an interface from the outside world to a computing system

Digital-to-Analog Converters

(DACs)

provide an interface

from a computing system to the outside world

2Slide3

Why This Course on Data Converters?

Needed to interface with

the physical world

Data converters are everywhere – huge market

Demand for increasing data converter performance keeps growing

System-on-a-chip applications mean that data converters are in truly mixed-signal applicationsData converters are typically the bleeding edge of analog/mixed-signal designData converters are notoriously difficult to design

3Slide4

Why is data converter design difficult?

Need high precision from imprecise partsVery large, complicated systems, so simulation is difficult (and sometimes impossible)

Many, many transistors – simulations can last hours/days

Convergence problems

These are mixed-signal systems

NoiseCouplingOften require advanced processing and/or post-fabrication correction

Laser trimmingFusesInteraction with DSPsThese techniques complicate design/simulationDifferent from other analog systemsDeal with large signals (not small-signal modeling)

Typical ADCs

Anti-aliasing filter to

bandlimit

the signal

Converts from continuous-time to discrete-time

(switched-capacitor techniques)

- Primary active element is the comparator

- Often includes a DAC

- Creates the digital word- Provides error correction- Time synchrony

6Slide7

Nyquist-Rate vs. Oversampled

Nyquist-Rate

Sample at a rate close to the

Nyquist

frequency

“Conventional” type of data convertersProvides the fastest sampling rates / bandwidthsOversampledSampling rate is much, much higher than the

Nyquist rate (typically at least 20 times higher)Often called “noise-shaping” circuitsProvides very high resolution7Slide8

Expectations Coming into Class

That you will participate!That you will actually do the reading

Emphasis on doing, simulating, and creating

That you remember (or can relearn) Cadence

That we will be able to find a time to meet outside of class time for brief project updates (for the final project)

A willingness to experiment and search for answers

9Slide10

Mechanics of Class

Several short announced quizzesCover recent reading material

Usually 15-20 minutes

Focus on understanding concepts, as opposed to solving problems

Reading synopses

Short write-ups on what you readIn-class summaries of a specific aspect/circuit (short explanatory presentation, usually just a few minutes)

Statement saying that you actually did the readingIn-class discussion and problemsClass time is a time for discussion, sharing ideas/designs, and getting questions answeredDesign reviews and project summariesEveryone participates! Please provide your input, suggestions, questions
