Abstract
A bias control circuit for controlling a bias circuit coupled to an amplifier transistor. The bias control circuit receives a control voltage, and actively adjusts an equivalent resistance of the bias control circuit responsive to the control voltage, wherein the equivalent resistance is established between a first node and a reference voltage. In one embodiment, when the control voltage is increased, the equivalent resistance is gradually decreased and a current drawn by the bias control circuit is gradually increased, resulting in a quiescent current of the amplifier transistor being gradually increased.
