Abstract

An apparatus for calibration of a signal converter is disclosed. This apparatus includes a first digital-to-analog converter (“DAC”) and a calibration system coupled to an output port of the first DAC. The calibration system includes a second DAC. The calibration system is configured to provide an adjustment signal responsive to a spurious spectral performance parameter in an output of the first DAC. The spurious spectral performance parameter is sensitive to a timing error associated with the first DAC. The calibration system is coupled to provide the adjustment signal to the first DAC to correct the timing error of the first DAC.
