Abstract
Methods and systems for optimizing amplifier operations are described. The described methods and systems particularly describe a feed-forward control circuit that may also be used as a feed-back control circuit in certain applications. The feed-forward control circuit provides a control signal that may be used to configure an amplifier in a variety of ways.

A system for optimizing amplifier operations, including:
- (a) an amplifier configured to receive an input signal and a control signal, and generate an output signal in response to the input signal and the control signal, the output signal having a desired characteristic that includes at least one of a power level, amplifier gain, a voltage range, or a current level, wherein the control signal modifies an operating characteristic of the amplifier;
- and
- (b) a feed-forward control circuit, coupled to the amplifier, configured to receive the input signal, analyze the input signal using a bandwidth detector, generate the control signal based on the analyzed input signal, and provide the control signal to the amplifier;
- wherein the feed-forward control circuit is further configured to receive as inputs at least one of (a) a control data signal from a control circuit and/or (b) at least one derived data signal from a measurement circuit, wherein any of such inputs may be used in addition to, or in lieu of, the input signal to generate the control signal;
- and
- wherein the at least one derived data signal represents one or more of:
- power level data obtained from a monitored output signal from the amplifier, temperature data, power supply data, battery data, biasing data, signal level data, voltage level data, frequency data, power level data, logic level conditions, switch position data, physical location data, mode of operation of the amplifier, a modulation format of the output signal, and/or load mismatch data.
