Abstract
A bias circuit includes a current generating circuit generating an internal base current based on a reference current, a bias output circuit generating a base bias current based on the internal base current and outputting the base bias current to an amplifying circuit, and a temperature compensation circuit regulating the base bias current based on a temperature voltage reflecting a change in ambient temperature.
