Abstract
An apparatus for calibrating a time-interleaved analog-to-digital converter including a plurality of time-interleaved analog-to-digital converter circuits is provided. The apparatus includes a clock generation circuit configured to generate a plurality of phase shifted clock signals for the plurality of time-interleaved analog-to-digital converter circuits and a reference clock signal. Further, the apparatus includes a reference signal generation circuit configured to generate a reference signal based on the reference clock signal. The reference signal is a square wave signal. The apparatus additionally includes a coupling circuit configured to controllably couple an input node of the time-interleaved analog-to-digital converter to either the reference signal generation circuit or to a signal node capable of providing an analog signal for digitization.
