Latest Patents
Chang-min Sim holds a patent titled "Decision feedback equalizer for minimizing number of comparators in decoder and operation method thereof." This invention discloses a decision feedback equalizer that includes a summator receiving a gray code-based PAM-4 signal, a first bit signal, and a second bit signal. The summator outputs an input voltage by adding a preset coefficient to the PAM-4 signal's voltage level based on the first and second bit signals. Additionally, the decoder receives this input voltage along with first to third reference voltages of the PAM-4 signal, outputting the first and second bit signals. The decoder comprises a first comparator that outputs the first bit signal by comparing the input voltage's magnitude with the first reference voltage, and a second comparator that outputs the second bit signal by comparing charge-discharge intensities of the input voltage with the second and third reference voltages. Chang-min Sim has 1 patent to his name.
