ABSTRACT:
A semiconductor integrated circuit having bias circuits each including different reference resistor is disclosed. The semiconductor integrated circuit comprises a reference voltage generating circuit which outputs a reference voltage, a first bias circuit connected to the reference voltage generating circuit. The first bias circuit has a first reference load element formed of a first material and generates a first bias voltage. The semiconductor integrated circuit further comprises a first driver circuit connected to the first bias circuit. The first driver circuit drives a first load element formed of the first material based on the first bias voltage. The semiconductor integrated circuit further comprises a second bias circuit connected to the reference voltage generating circuit and a second driver circuit connected to the second bias circuit. The second bias circuit has a second reference load element formed of a second material. The second driver circuit drives a second load element formed of the second material based on the second bias voltage.
