1. A laser driver to drive a semiconductor laser diode, said driver being driven by signals complementary to each other, comprising:

  • a first transistor with an enhancement type for receiving one of said signals with a normal phase, said first transistor being connected in parallel to said laser diode;

    a second transistor with said enhancement type, for receiving another one of said signals with an opposite phase, said second transistor being connected in parallel to said laser diode and having a size smaller than a size of said first transistor; and

    a terminator connected between a control electrode of said first transistor and a control electrode of said second transistor.
