  • Method of amplifying an input signal
    Patent number: 10651795
    Abstract: A method and a device for amplifying an input signal include a power amplifier for amplifying a binary input signal, a modulation device for generating the binary input signal on the basis of the input signal, the input signal being a complex-valued signal and the binary input signal being a real-valued signal, the modulation device including an adding device configured to add the complex-valued input signal to a complex-valued carrier signal of a predefined frequency and to thus generate a resulting complex-valued signal, and the modulation device including a combination device connected downstream from the adding device and configured to generate the real-valued binary input signal from the real part and the imaginary part of the resulting complex-valued signal by combining the real part and the imaginary part of the resulting complex-valued signal.

  • Apparatus for amplifying an input-signal
    Patent number: 8803608
    Abstract: Embodiments of the present invention provide an apparatus for amplifying an input-signal. The apparatus includes a switch-mode amplifier for amplifying a digital input-signal. The apparatus is characterized by a generator for generating the digital input-signal based on the input-signal, wherein the generator is configured to generate the digital input-signal such that the digital input-signal is located at a predefined frequency band and such that distortions are located at a frequency higher than the predefined frequency band.
