Modern successive-approximation analog-to-digital converter
ICs are replacing older current-mode D/A structures with
capacitor arrays, called CDACs (for Capacitor D/A). This
change makes it easier to combine the analog components of
the converter with the digital elements in standard CMOS
structures. Additionally, the capacitor input structure adds
inherent sampling to the A/D, at a time when more and more
A/D applications are involved in signal processing.
