Abstract
A power-amplifier arrangement () is disclosed. The power-amplifier arrangement () comprises a pulse modulator () adapted to receive a digital input signal of the power-amplifier arrangement () and generate, based on the digital input signal of the power-amplifier arrangement (), an output signal of the pulse modulator () with a plurality of quantization levels. The pulse modulator has a plurality of output ports (-_n) for representing the output signal of the pulse modulator (). Each output port (-_n) of the pulse modulator () is associated with a unique one of the quantization levels such that a signal output on the output port (-_n) adopts a first state when the output signal of the pulse modulator () equals or exceeds the associated quantization level, or, otherwise, a second state. A related radio-transmitter circuit and a related radio-communication apparatus are also disclosed.
