Abstract: |
A calibratable analog-to-digital converter system with a split analog-to-digital converter architecture including N Analog-to-Digital Converters (ADCs) each configured to convert the same analog input signal into a digital signal. Calibration logic is responsive to the digital signals output by the N ADCs and is configured to calibrate each of the ADCs based on the digital signals output by each ADC.
