发明名称 Calibration and compensation of delta sigma ADC's and DAC's by correlating noise signals
摘要 The present invention correlates noise from a delta sigma modulator with noise from the same modulator passed through a nonlinear block whose purpose is to isolate the imperfection being measured. Once the imperfection is measured the results may be used to correct the output of the delta sigma modulator, to accept or reject chips or for other purposes.
