ABSTRACT:
A signal transmission cable driver apparatus for transmitting an input signal through a transmission cable performs frequency compensation without using a peaking coil. The signal transmission cable driver apparatus includes a transmission driver for receiving the input signal and driving the transmission cable to transmit the input signal therethrough, and transition signal drive means having a capacitor circuit for detecting transition of the input signal by charge/discharge in the capacitor circuit and amplifying currents in said charge/discharge of the capacitor circuit, wherein the currents amplified by the transition signal drive means are superimposed on the input signal driven by the transmission driver at an input of the transmission cable.
