Latest Patents

One of Caspar Van Vroonhoven's key patents is the "Two-stage phase digitizer." This patent describes an analog-to-digital converter (ADC) that converts an analog signal into a digital value using a two-pass digitization process. In the first operation, coarse digitization is performed by an averaging converter based on a set of references. Then, in the second operation, fine digitization is executed by either another averaging converter or the same averaging converter based on a subset of the set of references that is progressively closer to the instantaneous value of the analog signal. For instance, the coarse digitization may be performed by a low-resolution ADC stage, while the fine digitization may be carried out by a sigma-delta ADC, such as a single-bit sigma-delta ADC. Additionally, the other averaging converter may utilize dynamic element matching to shuffle reference elements used to generate the subset. This innovative design allows the ADC to provide high resolution with reduced nonlinearity and quantization noise.
