  • Patent number: 8547270
    Abstract: A system for a successive-approximation-register analog-to-digital converter (SAR ADC) includes a gain trim module and an SAR control module. The gain trim module is configured to selectively trim a gain of a sub capacitive digital-to-analog converter (DAC) of the SAR ADC. The SAR control module controls the gain trim module based on an accumulated error associated with a main capacitive DAC of the SAR ADC.

  • Patent number: 8508398
    Abstract: A system for a successive-approximation-register analog-to-digital-converter (SAR ADC) includes a first capacitive digital-to-analog converter (DAC), first and second conversion control modules, and an SAR control module. The first capacitive DAC has a size less than a second DAC of the SAR ADC. The first conversion control module generates first and second signals for a comparator of the SAR ADC based on outputs of the first and second capacitive DACs and an analog input signal. The second conversion control module generates third and fourth signals for the SAR control module of the SAR ADC based on outputs of the comparator. The SAR control is configured to (i) control the first and second conversion control modules during a full conversion and a following partial conversion, (ii) determine an offset of the comparator, and (iii) control the SAR ADC based on the determined comparator offset.

  • Patent number: 8441386
    Abstract: A SAR ADC includes a DAC including a first set of capacitors each having a first end connected to a common node, and a second end, and a first set of switches each connecting the second end of a respective one of the capacitors to a first reference voltage. The SAR ADC further includes a second set of capacitors each having a first end connected to the common node and a second end that receives an input to be converted when the common node is connected to ground. The SAR ADC further includes a second set of switches that selectively connect the second end of a first capacitor of the second set of capacitors to ground when the input is disconnected from the second ends of the second set of capacitors and when the common node is disconnected from ground during a first of a plurality of successive approximations.
