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.
Claims19
A system for optimizing amplifier operations, including:
- (a) a scalable periphery amplifier configured to receive a radio frequency input signal, the scalable periphery amplifier including a plurality of selectable unit cells for providing an adjustable amount of gain to the input signal by applying the input signal to a selection of one or more of the plurality of selectable unit cells;
- and
- (b) a feed-forward control circuit, coupled to the scalable periphery amplifier and to the input signal, configured to receive the input signal and generate a control signal that is derived from at least one characteristic of the input signal and which is provided to the scalable periphery amplifier for adjusting the amount of gain of the scalable periphery amplifier.
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;
- (b) a temperature probe placed at a monitoring point in the amplifier and configured to output a data representing a temperature;
- (c) a measurement circuit coupled to the temperature probe and including at least a temperature detector configured to measure a temperature based on the temperature probe output data and to output a derived data signal as a function of such temperature measurement;
- and
- (d) a feed-forward control circuit including a look-up table, the feed-forward control circuit coupled to the amplifier, to the input signal, and to the measurement circuit, the feed-forward control circuit configured to receive the derived data signal and to receive and analyze the input signal, apply the analyzed input signal and the derived data signal to the look-up table to generate the control signal, and provide the control signal to the amplifier to modify at least one operating characteristic of the amplifier as a function of at least temperature, thereby altering the desired characteristic of the output signal.
