Abstract
In one embodiment, a method includes generating a first current in a bias current circuit and biasing an amplifier with the first current when the amplifier is operating in a first temperature range, and generating a second current in the bias current circuit and biasing the amplifier with the second current when the amplifier is operating in a second temperature range. These two currents may correspond to different profiles with respect to temperature, to maintain substantial linearity of the amplifier over the temperature ranges.
