Latest Patents

One of his latest patents is the "Body Bias Circuit and Body Bias Generation Method." This invention involves a body bias circuit designed to generate a body bias for a MOS switch. The circuit includes an intrinsic MOS device that shares the same conductivity type as the MOS switch and features an intrinsic threshold voltage. An operational regulation circuit is coupled to the intrinsic MOS device, generating the body bias based on the voltage of one terminal of the MOS switch and the intrinsic threshold voltage. This configuration ensures that the threshold voltage of the MOS switch inversely tracks the intrinsic threshold voltage, optimizing its performance during both conducting and non-conducting operations.

Another significant patent is the "Oversampling Data Recovery Apparatus and Method." This invention utilizes an open-loop data recovery approach that employs an oversampling technique. It counts the occurrence of data transitions to determine the appropriate sampling clock phase. The apparatus uses counters with variable thresholds to monitor phase transitions, allowing a phase selection circuit to identify the preferred phase for data recovery. The thresholds of the counters are adjusted based on the preferred phase, enhancing the accuracy of the sampled data recovery process.
