Abstract
A successive approximation register (SAR) analog-to-digital converter includes a capacitive digital-to-analog converter (CDAC), a comparator, and a SAR control circuit. The comparator is coupled to an output of the CDAC. The SAR control circuit is coupled to an input of the CDAC and to an output of the comparator. The SAR control circuit is configured to provide a feedback signal to the CDAC. The CDAC is configured to apply the feedback signal to form an infinite impulse response filter.
