Abstract
An integrated circuit device includes a semiconductor amplification element and a bias circuit for applying a bias voltage to the semiconductor amplification element. A power source of the bias circuit is connected to a power source of the semiconductor amplification element via a semiconductor element such that idle current of the semiconductor amplification element is changed in response to a change of a supply voltage of the semiconductor amplification element.
