|---|---|---|
Today's applications such as broadband satellite receivers, cable TVs, and software-defined radios require highly efficient ADCs with high sampling rates and high resolutions. A time-interleaved ADC (TIADC) is a popular architecture used to achieve this goal. However, this structure suffers from mismatches between the sub-converters, which cause errors on the output signal, and more significantly, decrease the SFDR. These mismatches can be a severe limitation in applications such as satellite reception, where both narrowband and wideband signals are used. This paper introduces digital derivative-based estimation of timing mismatches. Gain, offset and skew mismatch calibrations are performed entirely in the digital domain through equalization. |
