The compensation circuit comprises an oscillator, a first variable delay line, a second variable delay line, a phase detector and a controller. The oscillator generates an oscillation signal to input into a first transmission line and a second transmission line. The first variable delay line receives the oscillation signal transmitted through the first transmission line. The second variable delay line receives the oscillation signal transmitted through the second transmission line. The phase detector compares the phases of the two oscillation signals from the variable delay lines to generate a phase difference signal. The controller adjusts the variable delay lines to compensate for asynchronous signal transmission of the transmission lines according to the phase difference signal.
