Latest Patents
One of his latest patents is titled "Methods and apparatus for reducing timing-skew errors in time-interleaved analog-to-digital converters." This invention describes a time-interleaved analog-to-digital converter (ADC) architecture that employs a low-resolution coarse ADC channel. This channel samples an input analog signal at a Nyquist rate and facilitates background calibration of timing-skew error without interrupting normal operation. The coarse ADC channel provides a timing reference for multiple higher-resolution TI ADC channels, which sample the input signal at a lower sampling rate. By comparing the coarse ADC digital output to the respective TI ADC digital outputs, the system can variably adjust the sampling clocks of the TI ADC channels to align them with the coarse ADC channel, thus reducing timing-skew error.
Another notable patent is "Level-crossing based circuit and method with offset voltage cancellation." This invention includes a level-crossing based circuit with offset voltage cancellation. It features a first level-crossing detector section that charges an output capacitor to a voltage corresponding to an input signal, which includes a first offset voltage. Additionally, a second level-crossing detector section discharges another output capacitor to a second voltage that includes a second offset voltage, which is equal in magnitude but opposite in polarity to the first offset voltage. This innovative approach enhances the accuracy of signal processing.
