    Abstract: A self-calibrating analog-to-digital converter (ADC). The ADC includes multiple component ADCs to generate respective digital representations of an input signal in response to respective timing signals that are offset in phase from one another, each component ADC having a gain setting that controls a magnitude of the digital representations. The ADC further includes correction circuitry to generate a plurality of fast-Fourier transforms (FFTs) that correspond to the digital representations of the input signal and to adjust the gain settings of the component ADCs and/or phase angles of the timing signals based on gain and phase errors indicated by the FFTs.

    Abstract translation: 自校准模数转换器（ADC）。 ADC包括多个分量ADC，以响应于彼此相位偏移的相应定时信号来产生输入信号的相应数字表示，每个分量ADC具有控制数字表示幅度的增益设置。 ADC还包括校正电路，用于产生对应于输入信号的数字表示的多个快速傅里叶变换（FFT），并且基于增益来调整分量ADC的增益设置和/或定时信号的相位角 和由FFT表示的相位误差。
