Pilot-tone calibration for time-interleaved analog-to-digital converters

摘要: 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 timing signals that are offset phase from one another, each having a gain setting controls magnitude the representations. further correction circuitry plurality fast-Fourier transforms (FFTs) correspond and adjust settings and/or angles based on errors indicated by FFTs.
