Flexible ADC Calibration Technique Using ADC Capture Memory

摘要

Systems and methods are provided for calibrating an analog to digital converter (ADC) using one or more feedback mechanisms. In an embodiment, a capture memory module captures a portion of ADC data and post-processes the captured data using a microprocessor to perform calibration. Using the microprocessor, the capture memory module calibrates the ADC until the output of the ADC is within a desired range. In an embodiment, the capture memory module also captures a portion of data output from a digital correction module and post-processes this captured data using the microprocessor. Using the microprocessor, the capture memory module calibrates the digital correction module until the output of the digital correction module is within a desired range
