Improved dynamic compensation of ADCs using an iterative estimate of the ADC calibration signal

An iterative improvement of current analog to digital converter (ADC) dynamic compensation schemes is introduced. The improved calibration procedure uses an improved estimate of the ADC input during calibration. Simulation results which implement the algorithm demonstrate an improvement in the spuri...

Summary:An iterative improvement of current analog to digital converter (ADC) dynamic compensation schemes is introduced. The improved calibration procedure uses an improved estimate of the ADC input during calibration. Simulation results which implement the algorithm demonstrate an improvement in the spurious free dynamic range for a compensated 8-b converter of 30 to 40 dB over the performance of the uncompensated converter.< >
