Latest Patents

One of his latest patents is a phase lock loop device. This device includes a probability shaping device positioned between a phase detection device and a charge pump and loop filter (CPLF) device. The probability shaping device functions to reduce the frequency of outputting up-index or down-index, thereby shaping the probability distribution to minimize degradation caused by mismatching of the CPLF device. Another significant patent is a clock data recovery circuit with a phase decision circuit. This circuit features a feedback type phase discrimination and has an output signal of B bits. It comprises a sampler, a phase region decision circuit, a phase status register, and a multiplexer. The sampler oversamples k*B bits per cycle from a data input signal based on a sampling clock signal. The phase region decision circuit generates multiple binary up-down decision signals according to the oversampled data input signal and a current phase status signal. The phase status register produces the current phase status signal based on the binary up-down decision signals, while the multiplexer selects data of B bits from the oversampled data input signal according to the current phase status signal.
