Claim Text:
1. A device for performing amplification of an input signal using dynamic feedback comprising: an amplifier adapted to amplify the input signal by a gain factor; one or more feedback paths coupled to an output and an input of the amplifier for conveying a feedback signal from an output signal of the amplifier to the input of the amplifier, wherein the one or more feedback paths includes one or more gain control elements for adjusting the magnitude of the feedback signal; and a controller coupled to the input of the amplifier prior to the one or more feedback paths and further coupled to the one or more gain control elements in the one or more feedback paths, wherein the controller is adapted to apply control voltages to the one or more gain control elements based on a lookup table containing control voltages to be applied to the one or more gain control elements based on the input signal and one or more of the output signal, a temperature of the amplifier, a length of time the amplifier has been operating, a prior state of the input signal, a supply voltage to the amplifier, and humidity.
