Latest Patents
Wei-Chien Chiu 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 connected 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 that is 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. Wei-Chien Chiu's innovative approach has resulted in 1 patent.
