Abstract
A circuit for compensating for mismatch in a plurality of channels of a time-interleaved analog-to-digital converter is described. The circuit comprises an analog-to-digital converter circuit of a first channel of the plurality of channels configured to receive an analog input signal and to generate a digital value associated with the analog input signal; an arithmetic circuit configured to receive the digital value generated at the output of the analog-to-digital converter; a memory element configured to receive an output of the arithmetic circuit; and an accumulator circuit coupled to the memory element, wherein the accumulator generates an average value that is provided to the arithmetic circuit to modify the digital value generated at the output of the analog-to-digital converter while receiving the analog input signal.
