Abstract
Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a bias controller for an amplifier circuit involves obtaining temperature data corresponding to a temperature of the amplifier circuit, generating a proportional to absolute temperature (PTAT) bias voltage based on a first PTAT slope when the temperature is within a first range of temperatures or a second PTAT slope when the temperature is within a second range of temperatures, wherein the second PTAT slope is greater than the first PTAT slope, and biasing the amplifier circuit based on the generated PTAT bias voltage.
