Abstract
A driver circuit having a temperature correction circuit for producing an output signal with high precision amplitude and timing by correcting the temperature changes in the amplitude and timing. The temperature correction circuit includes a temperature detector for detecting the temperature change in output elements, a timing adjustment circuit for correcting the timing of an output signal relative to an input signal upon receiving the temperature detection signal from the temperature detector, and a bias circuit for correcting the output amplitude and impedance of the output signal.
