Latest Patents

One of Ng's latest patents is titled "Timing recovery for partial-response maximum likelihood sequence detector." This invention presents a technique for timing recovery that involves a frequency acquisition loop locking a voltage-controlled oscillator (VCO) clock of a multi-band VCO to a reference clock. The frequency acquisition loop generates first and second feedback clocks from the VCO clock. Additionally, a data lock phase loop generates a driving signal corresponding to a phase error signal from interleaved partial response signal (PRS) samples based on the second feedback clock. This driving signal controls the multi-band VCO in a data phase lock mode. A lock detect controller is also included, which detects a frequency lock condition in a frequency lock mode and a data lock condition in the data phase lock mode based on the first feedback clock and the reference clock.

Another significant patent by Ng is the "Filter tuner system and method." This system comprises sequential logic, a register, a comparator, first and second counters, synchronizing logic, first and second oscillators, control logic, and first and second combinational logic. The method involves executing a calibration cycle of a filter tuner, a measurement cycle of the filter tuner, and tuning a filter with the filter tuner based on a determined cutoff frequency variation.
