Latest Patents

Among his latest patents, Lee developed a receiver for removing intersymbol interference. This innovative device features a sampling circuit designed to sample a comparison result between an input signal and multiple threshold voltages based on a sampling clock signal. A clock controller generates this sampling clock signal, while a control circuit produces both the clock control signal and the threshold voltages according to a specific target value and the output of the sampling circuit. The control circuit adjusts the ratio of the main cursor's magnitude and the pre-cursor intersymbol interference's magnitude to achieve the desired target value.

Another significant patent involves a receiver equipped with a multi-rate equalizer. This receiver incorporates an equalization circuit, which produces a data sample signal and an edge sample signal by sampling the data input signal in accordance with a clock signal. The equalization operation is performed based on these signals, with a clock gate circuit that selectively chooses clock signals from among a range of multi-phase clock signals based on a selection signal.
