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.
