Latest Patents

One of Chen's latest patents is the "Peak detector and detecting method thereof." This invention provides a peak detector that features input signal triggering control and low-frequency energy attenuation capability. The peak detector includes a charging unit and a discharging unit. The charging unit is triggered by a peak value detected in a received input signal, allowing it to charge an electrical charge storage unit, such as a capacitor, for a predetermined duration. Following this, the discharging unit discharges the storage unit before the next peak value is detected.

Another significant patent is the "Oversampling data recovery apparatus and method." This invention utilizes an open-loop data recovery technique that counts the occurrence of data transitions to determine the appropriate sampling clock phase. The apparatus employs counters with variable thresholds to monitor phase transitions, allowing for the selection of a preferred phase for the recovery of sampled data.
