摘要：The successive approximation register (SAR) type is potentially the most accurate ADC circuit. As it takes N cycles for the ADC to complete a conversion, the speed of the converter is limited by the output settling time of the DAC and the time needed by the comparator to resolve the input difference in each 1-bit cycle. In this paper, the effects that influence the speed of the ADC are president, the model of the conversion time for the ADC is set up, and guides for the circuit designers to realize quick design are provided.
