Abstract
An analog-to-digital converter (ADC) includes a capacitive digital-to-analog converter (CDAC), a comparator, and a successive approximation register (SAR) control circuit. The comparator is coupled to an output of the CDAC. The SAR control circuit is coupled to an output of the comparator and to an input of the CDAC. The SAR control circuit includes a flip-flop. The flip-flop includes a clock input terminal, a data input terminal, and an output. The clock input terminal is coupled to the output of the comparator. The data input terminal coupled to a constant voltage source. The flip-flop can include an enable input terminal coupled to a SAR state circuit. The output is coupled to the CDAC.
