Abstract:
A mismatch corrector can include a correction path comprising a plurality of parallel branches that each includes a correction filter that applies a respective one of a plurality of time domain filter coefficients that corresponds to a function of a mismatch profile of an interleaved analog-to-digital (IADC) signal on the IADC signal. The mismatch corrector can also include a delay path that delays the IADC signal by a predetermined number of samples to provide a delayed version of the IADC signal. The mismatch corrector can further include a summer to subtract an output of each correction filter from the delayed version of the IADC signal to generate a corrected IADC signal.
