The approach to the antialiasing-filter design for the delta-sigmadata converter is significantly different from the approach youwould use for a SAR (successive-approximation register) orpipeline ...
A new 18-bit successive-approximation-register (SAR) converter and a 20-bit delta-sigma unit expand the speed and accuracy envelopes for analog-to-digital converters (ADCs). Made by Analog Devices, ...
