Latest Patents

Sourya Dewan holds a patent for "Calibration in non-linear multi-stage delay-to-digital conversion circuits." This invention involves a delay-domain analog-to-digital converter that includes a voltage-to-delay circuit and a time-to-digital converter circuit. The voltage-to-delay circuit generates a delay signal based on the applied calibration voltage. This delay signal is then applied to a first residue stage, which is configured to generate a sign bit and a residue delay signal. The residue delay signal is subsequently applied to the input of a successive residue stage, which also generates a sign bit and provides a residue delay signal to the inputs of the next successive residue stage. Additionally, first and second trim circuits are incorporated in a delay comparator of one of the successive residue stages. These circuits are designed to adjust the first response of the residue stage for a calibration voltage in a first range and to adjust the second response of the residue stage for a calibration voltage in a second range. Sourya's innovative approach enhances the accuracy and efficiency of delay-to-digital conversion processes.
