Abstract
The present invention is directed to signal processing systems and methods thereof. In various embodiments, the present invention provides an analog-to-digital conversion (ADC) system that includes a flash ADC portion and a time-interleaved parallel SAR portion. For an n-bit ADC process, the flash ADC portion converts k MSBs of the n bits during a single cycle, and the SAR portion converts n−k LSBs in m number of cycles. The SAR portion includes a number of SAR channels that perform A/D conversion in parallel, and the k MSB from the course flash converter is verified for errors by the SAR portion and allows a net saving of the power consumption by reducing the number of fine resolution SARs. There are other embodiments as well.
