Time-interleaved analog-to-digital converter system

Abstract:

A time-interleaved Analog-to-Digital Converter, ADC, system is provided. The time-inter-leaved ADC system includes time-interleaved first and second ADC circuits and a switching circuit. The switching circuit is configured to selectively supply an analog input signal for digitization to at least one of the first ADC circuit, the second ADC circuit or ground, and to selectively supply an analog calibration signal to at least one of the first ADC circuit, the second ADC circuit or ground. Further, the time-interleaved ADC system includes an output circuit configured to selectively generate, based on least one of a first digital signal output by the first ADC circuit and a second digital signal output by the second ADC circuit, a digital output signal.
