Abstract: A time-interleaved (TI) analog-to-digital converter (ADC) architecture employs a low resolution coarse ADC channel that samples an input analog signal at a Nyquist rate and facilitates background calibration of timing-skew error without interrupting normal operation to sample/convert the input signal. The coarse ADC channel provides a timing reference for multiple higher resolution TI ADC channels that respectively sample the input signal at a lower sampling rate. The coarse ADC digital output is compared to respective TI ADC digital outputs to variably adjust in time corresponding sampling clocks of the TI ADC channels so as to substantially align them with the sampling clock of the coarse ADC channel, thus reducing timing-skew error. In one example, the coarse ADC output provides the most significant bits (MSBs) of the respective TI ADC digital outputs to further improve conversion speed and reduce power consumption in these channels.
