ABSTRACT:
A bias circuit supplies a predetermined current to a next-stage circuit. The bias circuit comprises a first node having a first potential, a second node having a second potential, an output node electrically connected to the next-stage circuit, a main bias circuit electrically connected to the first node and the output node and for supplying the predetermined current from the first node to the output node, and an auxiliary bias circuit electrically connected to the first and second nodes and the output node and for equalizing the value of a current flowing from the first node to the output node to the value of a current flowing from the output node to the second node.
