The present invention provides a circuit for generating a bias voltage for a high speed input/output pad. To this end, a bias voltage generator according to an embodiment of the present invention is to supply at least one bias voltage to a buffer circuit connected to the pad, which includes: a bias generation part for generating a first bias voltage; and a reference voltage generation part for generating a voltage proportional to the pad voltage applied to the pad as a reference voltage, wherein the first bias voltage may be the sum of the reference voltage and a predetermined voltage. |
