    摘要: Various multi-lane ADCs are disclosed that substantially compensate for impairments present within various signals that result from various impairments, such as phase offset, amplitude offset, and/or DC offset to provide some examples, such that their respective digital output samples accurately represent their respective analog inputs. Generally, the various multi-lane ADCs determine various statistical relationships, such as various correlations to provide an example, between these various signals and various known calibration signals to quantify the phase offset, amplitude offset, and/or DC offset that may be present within the various signals. The various multi-lane ADCs adjust the various signals to substantially compensate for the phase offset, amplitude offset, and/or DC offset based upon these various statistical relationships such that their respective digital output samples accurately represent their respective analog inputs.

    摘要: Various pipeline ADCs are disclosed that substantially compensate for interference or distortion that results from imperfections with various ADC modules of the pipeline ADCs. The pipeline ADCs include various ADC stages and various compensation stages that are coupled to the various ADC stages. The various ADC stages convert their corresponding analog inputs from an analog signal domain to a digital signal domain to provide various digital output signals and various analog residual signals to subsequent ADC stages. The various compensation stages compensate for interference or distortion that is impressed onto the various analog residual signals which results from imperfections within previous ADC stages.

    摘要: A method and apparatus is disclosed to compensate for impairments within a data converter such that its output is a more accurate representation of its input. The data converter includes a main data converter, a reference data converter, and a correction module. The main data converter may be characterized as having the impairments. As a result, the output of the main data converter is not the most accurate representation of its input. The reference data converter is designed such that the impairments are not present. The correction module estimates the impairments present within the main data converter using its output and the reference data converter to generate corrections coefficients. The correction module adjusts the output of the main data converter using the corrections coefficients to improve the performance of the data converter.
