Abstract
An electronic circuit comprises multiple analog-to-digital converters (ADCs), clock circuitry, and calibration circuitry. The clock circuitry is configured to provide clock signals to the multiple ADCs to advance the multiple ADCs through time-interleaved analog-to-digital (A/D) conversions. The calibration circuitry is configured to determine a magnitude of timing skew error between any two of the clock signals; apply a dither sequence to a first clock signal of the any two clock signals, wherein the first clock signal is applied to a first ADC; determine a polarity of the timing skew error by determining a polarity of gain experienced by the dither sequence from the time-interleaved A/D conversions.
