Abstract
A successive approximation register analog-to-digital converter (SAR ADC) includes a comparator coupled to receive a sampled input voltage; a pair of arrays each including individually switchable binary-weighted capacitors that are switchably coupled to an output of the comparator via phase switches, respectively. A phase signal for controlling a corresponding phase switch associated with a current bit becomes asserted when a preceding bit finishes comparison, and the phase signal becomes de-asserted when the current bit finishes comparison.
