Successive Approximation Register Analog-to-Digital Converter With Single-Ended Measurement

摘要

A circuit may include a comparator having a first input, a second input, and an output. The circuit further may further include a successive approximation register (SAR) circuit coupled to the output of the comparator, the first input, and the second input. The SAR circuit may be configured to program one or more capacitors to selectively bias the first input to provide a single-ended measurement of a voltage at the second input.
