Latest Patents
Yi-Chung Chen holds a patent for a "Multi-step analog/digital converter and on-line calibration method thereof." This invention introduces an on-line calibration method that utilizes two calibration algorithms running in the background without interrupting the normal operation of the analog signal process. The method includes performing a residue amplifier gain error calibration and a DAC non-linearity calibration. The residue amplifier gain error calibration reduces the gain error of the residue amplifier for a missing code or a missing decision level phenomenon. The DAC non-linearity calibration relaxes the matching requirement of passive components in current semiconductor processes. The invention features a two-step ADC (Analog-to-Digital Converter), which includes a first signal processing unit, a second signal processing unit, a programmable gain control unit, and a programmable reference voltage generator, all performing the on-line calibration method.
