Latest Patents

One of his latest patents is titled "Data slicer and data slicing method for optical disc system." This invention involves a data slicer that converts an analog input signal into a digital signal. The data slicer includes a comparator, a duty detector, and a low pass filter. The comparator compares the analog input signal with a feedback signal to generate the digital signal. The duty detector detects the duty of the digital signal and converts it if necessary. The low pass filter integrates the output signal to generate the feedback signal.

Another significant patent is "Defect detection in an optical disk data reproduction system." This invention provides a method for detecting disk defects in an optical disc data reproduction system. It allows for accurate detection of defects during both constant linear velocity and constant angular velocity modes. The circuit includes a comparator that generates comparison signals based on the RF signal levels. A defect detector then generates a defect detecting signal based on these comparison signals.
