Abstract
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.
Claims10
Power amplification device, comprising an input for receiving a signal having a useful frequency band, and power amplification means of the delta-sigma type, characterized in that the power amplification means of the delta-sigma type (MAP) exhibit an order greater than or equal to one in the useful band of the signal and an order greater than or equal to one outside the said useful band.
Device according to one of the preceding claims, characterized in that it comprises at least one signal amplifier (k6, k10) connected between the said input and the power amplification means.
Device according to one of the preceding claims, characterized in that it is embodied in the form of an integrated circuit.
