Introduction

Wai Lau is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of integrated tuner technology, particularly with his innovative patent that enhances television signal processing.

Latest Patents

Wai Lau holds a patent for an invention titled "On-chip R-C time constant calibration." This integrated tuner includes circuitry designed to receive a television signal, a quadrature mixer coupled to the output of the circuitry, and a polyphase filter linked to the output of the quadrature mixer. The invention also features a relaxation oscillator and a digital calibration module. The relaxation oscillator generates a clock with a period directly proportional to the on-chip RC time constant. This clock is fed into a counter within the digital calibration module, which is started and stopped at predefined time intervals by a finite state machine. The finite state machine updates the calibration code based on a successive approximation algorithm according to the end count results received from the counter. The digital calibration module then outputs the updated calibration code to both the polyphase filter and the relaxation oscillator. Wai Lau's innovative approach has led to advancements in the efficiency and accuracy of television signal processing.
