Design
Project: Analog-to-Digital Converters
Introduction
The design project offers you the opportunity to carry out a complete design
process for a realistic and practical system.
Analog-to-digital converters, also called A/D or ADC, convert an analog
signal quantity into a numerical quantity for use in a digital system. A/D
converters find application in instruments such as digital multimeters, audio
samplers, soundcards, and digital oscilloscopes. Many different types of
analog-to-digital converter circuits have been developed to suit a wide range
of applications. A/D converter types can be distinguished by key features such
as number of bits of resolution, conversion speed, linearity, and digital
interface technique.
In this three-week project, you will design, build, and evaluate one ADC
device: either the tracking converter or the ramp converter. Both
devices use the same hardware connections outside of the FPGA, so you should
work jointly on that aspect of the design. However, the remaining design
activities must be carried out independently. You will present your design and
results in a formal report. Each student is graded individually on this
project. Students may not team up with other students who are working on
the same ADC.
