Abstract
An electronic circuit comprises multiple analog-to-digital converter (ADC) circuits and control logic circuitry. The control logic circuitry advances the multiple ADC circuits through multiple time-interleaved conversions that include time-interleaved acquisition phases, conversion phases, and tracking phases. An acquisition phase of a first ADC circuit samples the analog signal, a conversion phase of the first ADC circuit converts the sampled analog signal to a digital value, and the control logic circuitry is configured to update the first ADC circuit with most recent A/D conversion information by a different ADC circuit during a tracking phase of the first ADC circuit before the acquisition phase of the first ADC circuit.
