Abstract

See full text

A calibration circuit for a time-interleaved analog-to-digital converter includes a filter circuit and a calculating circuit. The filter circuit is configured to receive a first signal and generate a second signal based on the first signal. The first signal comprises an image of an interference signal, the second signal comprises a reconstructed image of the interference signal, and a frequency of the reconstructed image of the interference signal is the same as a frequency of the image of the interference signal. The calculating circuit is configured to cancel the image of the interference signal of the first signal according to the second signal.
