摘要： An analog-to-digital converter (ADC) including a plurality of comparators connected to the ADC. The ADC further includes a first pair of terminals and a second pair of terminals connected to each of the plurality of comparators. The ADC further includes a first pair of switches coupled to each of the first pair of terminals and a second pair of switches coupled to each of the second pair of terminals, where the first and second pair of switches are configured to alternate a corresponding comparator between normal operation and a calibration configuration. Comparators other than the corresponding comparator are configured for normal operation if the corresponding comparator is configured to be calibrated.

摘要： A method of calibrating a digital-to-analog converter (DAC) is provided. The DAC includes a least-significant bit (LSB) block, and dummy LSB block adjacent to the LSB block. The DAC has a most-significant bit (MSB) block, which includes MSB thermometer macros. The method includes measuring the dummy LSB block to obtain a dummy LSB sum; and calibrating the MSB block so that each of the MSB thermometer macros provides a substantially same current as the dummy LSB sum.

摘要： Mechanisms to calibrate a digital to analog converter (DAC) of an SDM (sigma delta modulator) are disclosed. An extra DAC element in addition to the DAC is used to function in place of a DAC element under calibration. A signal (e.g., a random sequence of −1 and +1) is injected to the DAC element under calibration, and the estimated error and compensation are acquired.

摘要： An analog to digital convertor (ADC) includes a plurality of comparators one of which is referred to as an auxiliary comparator (e.g., comparator “Aux”). This comparator Aux is calibrated in the background while other comparators function as usual. Once having been calibrated, the comparator Aux replaces a first comparator, which becomes a new comparator Aux, is calibrated, and replaces the second comparator. This second comparator becomes the new comparator Aux, is calibrated, and replaces the third comparator, etc., until all comparators are calibrated. In effect, at any one point in time, a comparator may be calibrated as desire while other comparators and thus the ADC are operating as usual.
