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.
Claims20
A signal amplification circuit including:
- (a) an amplifier configured to receive an input signal and a control signal configured to modify an operating characteristic of the amplifier, and to generate an output signal having a desired characteristic in response to the input signal and the control signal;
- (b) a control circuit configured to output a control data signal;
- (c) a measurement circuit including at least one detector or analyzer configured to measure a selected characteristic of at least one data signal input or monitored signal input and to output at least one derived data signal as a function of the measurement;
- and
- (d) a feed-forward control circuit, coupled to the amplifier, the control circuit, and the measurement circuit, the feed-forward control circuit configured to receive the input signal, analyze the input signal using an input signal monitoring circuit, generate the control signal based on the analyzed input signal and the at least one of the control data signal and the at least one derived data signal, and provide the control signal to the amplifier for impressing the desired characteristic upon the output signal.
