Abstract
A circuit and method for calibrating ADCs and DACs generates a calibration signal by a DAC; filters spurs from the calibration signal from the DAC to generate a filtered calibration signal; calculates ADC interleave calibration factors to improve performance metrics of the ADC, responsive to the filtered calibration signal; receives the calibration signal from the DAC and calculates DAC interleave calibration factors; generates a calibration signal with improved performance metrics, responsive to the DAC interleave calibration factors received from the ADC; and repeats the process until the performance of the ADC and DAC are within a predetermined range.
