Abstract
Disclosed is a bias circuit which includes a bias voltage generating part configured to generate a bias voltage using a reference current and a variable current; a reference current source part configured to provide the reference current to the bias voltage generating part; and a current adjusting part configured to provide the variable current to the bias voltage generating part and to adjust the amount of the variable current according to voltage levels of at least two input signals. The bias circuit prevents an increase in power consumption and improves a slew rate at the same time.
