Abstract
Disclosed is an integrated circuit including a first bias current generating circuit. The first bias current generating circuit includes a first amplifier receiving a reference voltage and a first voltage and amplifying a difference between them to output a first output voltage, a first bias current generator receiving the first output voltage and outputting a first bias current in response to the first output voltage, a variable resistor receiving the first bias current and outputting the first voltage in response to the first bias current and a calibration code, a second bias current generator receiving the first output voltage and outputting a second bias current to a peripheral circuit in response to the first output voltage, and a third bias current generator receiving the first output voltage and outputting a third bias current to an external device through a first pad in response to the first output voltage.
