Latest Patents

Rafael holds a patent for a two-stage analog-to-digital converter designed for high-speed image sensors. This invention relates to a two- or multiple-stage analog-to-digital converter that includes an incremental ADC in the first stage. The incremental ADC comprises an integrator and a comparator. After a predefined number of comparisons performed by the comparator, the output of the integrator, appropriately scaled, is provided to the second stage for further sampling. Notably, the scaling gain is inversely proportional to the integrator gain. The second ADC is responsible for converting the remaining least significant bits, and the outputs of both stages are combined. Additionally, the invention includes calibration and correction approaches for the multi-stage ADC.
