PURPOSE: A bias voltage generation circuit is provided to prevent malfunction of a semiconductor device by generating a sinking current of a circuit for transmitting and generating a swing signal in a CML(Current Mode Logic) region. CONSTITUTION: A voltage comparator(400) compares the potential levels of a reference voltage and a feedback voltage. A feedback voltage generator(420) drives a feedback voltage terminal with a first driving current. A CML bias voltage generator(440) drives a CML bias voltage terminal with a second driving current. |
