About This Chapter
The scale of analog integrated circuits (ICs) and the analog portion of mixed-signal ICs is usually relatively small compared to digital IC counterparts—hundreds of devices in an analog circuit compared to millions to hundreds of millions of devices in a digital circuit. However, testing analog circuits poses a number of unique testing problems when compared to digital circuits and, as a result, requires a variety of different and unique test architectures and approaches. For example, there are no analog fault models that have been widely accepted, as is the case in digital testing. ...
