ABSTRACT:
A bias circuit which applies a bias voltage to a control terminal of a first active element for an RF signal amplification, includes a threshold voltage change compensation circuit and a first temperature compensation circuit. The threshold voltage change compensation circuit contains a second active element and compensates the bias voltage based on a change in threshold voltage of the first active element by using the second active element. The first temperature compensation circuit is connected between the control terminal and the voltage change compensation circuit and configured to compensate a change in the bias voltage based on a temperature change.
