CALIBRATION OF ANALOG-TO-DIGITAL CONVERTER DEVICES

摘要

Disclosed herein are systems for calibrating an analog-to-digital converter (ADC) device, as well as related devices and methods. In some embodiments, a system for calibrating an ADC device may include an ADC device, wherein the ADC device includes an ADC and a dither source, and wherein the ADC device is to apply a set of calibration parameters to generate digital outputs. The system may also include calibration circuitry, coupled to the ADC device, to determine which of multiple sets of values of calibration parameters results in the digital outputs having the lowest amount of noise, and to cause the ADC device to apply the calibration parameters associated with the lowest noise.

1. A system for calibrating an analog-to-digital converter (ADC) device, comprising:
the ADC device, wherein the ADC device includes an ADC and a dither source, and wherein the ADC device is to apply a set of calibration parameters to generate digital outputs; and calibration circuitry, coupled to the ADC device, to:
determine a first amount of noise in a first plurality of digital outputs generated by the ADC device when the ADC device applies first values of the set of calibration parameters;determine a second amount of noise in a second plurality of digital outputs generated by the ADC device when the ADC device applies second values of the set of calibration parameters;determine that the second amount of noise is greater than the first amount of noise; andin response to the determination that the second amount of noise is greater than the first amount of noise, cause the ADC device to apply the first values of the set of calibration parameters.
