Transmission line loss compensation circuit and transmission line loss compensation method

摘要

A transmission line loss compensation circuit and transmission line loss compensation method is provided. The transmission line loss compensation circuit includes a linear equalizer that compensates for a transmission line loss of high frequency components, a high-pass filter that extracts high frequency components from an output of the linear equalizer, a peak detector that compares the peak voltage of a high-pass filter output to first and second reference voltages, and a control circuit that controls the compensation intensity of the linear equalizer based on the detection results of the peak detector so that the peak voltage becomes an intermediate voltage between the first reference voltage and the second reference voltage.
