摘要： Systems and methods are provided for calibrating the control mechanism in a communication circuit to allow the communication circuit to maintain a desired output power level. The communication circuit includes a variable gain adjustment circuit and a power amplifier, which operate together to provide an output power level. A control circuit controls the variable gain adjustment circuit based on a default gain parameter, a high power threshold, and a low power threshold. A calibration circuit in the control circuit calibrates a default gain parameter to provide a desired output power. A power detector can detect the desired output power level to provide an output power measurement. The calibration circuit calibrates upper and lower power thresholds to provide an acceptable range of power variation around the output power measurement.

摘要： A system for communicating information includes a variable gain amplifier (VGA) responsive to an input signal and a gain control signal for controlling a gain of the VGA. The system also includes a power amplifier responsive to the VGA. An output power level of the power amplifier is compared to a predetermined reference value to generate the gain control signal. The gain control signal is offset by a gain offset value. To change the output power level of the power amplifier from a first output power level to a second output power level, a first predetermined reference value and a first gain offset value associated with the first output power level are changed substantially concurrently to a second predetermined reference value and a second gain offset value, respectively, associated with the second output power level.

摘要： A system comprises a variable gain amplifier (VGA) that amplifies an input signal with a gain that is based on a gain control signal. A power amplifier receives an output of the VGA. Memory switches between at least two of N output power settings each including a predetermined reference value and a predetermined gain offset value. The memory substantially concurrently changes from the predetermined reference value and the predetermined gain offset value of a prior one of the N output power settings to the predetermined reference value and the predetermined gain offset value of a current one of the N output power settings, where N is an integer greater than one. A gain control adjuster adjusts the gain control signal based on an output of the power amplifier and the predetermined reference value and gain offset value of the current one of the N output power settings.

摘要： Apparatus, systems, and methods implementing techniques for filtering signals are described. A filter circuit receives an input signal and produces a corresponding filtered signal. The filter circuit has a transfer function that relates the filtered signal to the input signal. The transfer function includes at least one pole and at least one zero, where at least one of the zeros corresponds to a first frequency, and at least one of the poles corresponds to a second frequency. The apparatus also includes a negative-transconductance circuit that is coupled to the filter circuit and that increases a magnitude of a component of the filtered signal that corresponds to the second frequency.

摘要： Apparatus, systems, and methods implementing techniques for reducing the variation of a DC offset are described. An input signal is amplified to produce an intermediate signal. The intermediate signal is processed to produce a feedback signal and an output signal, where the output signal has a DC offset that varies with a varying parameter of the circuitry used to process the intermediate signal. Variation of the DC offset of the output signal is reduced using the feedback signal. In one implementation, the circuitry used to process the intermediate signal is a variable-gain amplifier circuit, and the DC offset of the output signal varies with a gain of the variable-gain amplifier.
