Latest Patents
Hwaseok Shin holds a patent for a "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 voltage level of the PAM-4 signal based on the first and second bit signals. Additionally, the decoder receives the input voltage and 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 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. This patent showcases his innovative thinking and technical expertise.
