摘要： A power amplification device includes an input for receiving a signal having a useful or desired frequency band, and power amplification circuitry of the delta-sigma type connected to the input. The power amplification circuitry exhibits an order greater than or equal to one in the useful frequency band, and an order greater than or equal to one outside the useful frequency band.

摘要： Filtered digital information representative of the power of an output signal from an amplifier is generated, and control information from a setpoint representative of a desired power for the output signal is generated from the desired response time for the establishment of the power and from a model to be followed for the establishment. In addition, a gain control and a bias current control are established for each initial variable-gain amplifier from the filtered digital information, from the control information and from a polynomial digital regulation of the RST type whose polynomial coefficients are determined from input parameters comprising characteristics of each variable-gain amplifier and from characteristics of the filter generating the filtered digital information.

摘要： A power amplification device includes an input for receiving a signal having a desired frequency band. The signal also has a transfer function associated therewith. The power amplification device further includes power amplification circuitry having an order greater than or equal to one, and signal amplifiers connected between the input and the power amplification circuitry. Each signal amplifier has a predetermined gain so that zeros of the transfer function are outside the desired frequency band.
