摘要： A transmitter comprises a power amplifier which has an amplifier power-supply input and an output to supply a transmission signal with an output power. A power supply has power supply outputs to supply a first power supply voltage and a second power supply voltage. A switching circuit is arranged between the power supply outputs and the amplifier power-supply input. A controller has an input to receive a power change command to control: first the switching circuit to supply the first power supply voltage to the amplifier power-supply input, and the power supply to vary a level of the second power supply voltage, the level of the second power supply voltage being lower or higher than a level of the first power supply voltage if the power change command indicates that the output power has to decrease or increase, respectively, and secondly the switching circuit to supply the second power supply voltage to the amplifier power-supply input.

摘要： The present invention relates to a power amplifier being preferably applied in mobile communication devices andusing an envelope tracking technique. It is the object of the invention to improve a power amplifier with respect to its efficiency by simultaneously enabling an adaptation of the supply voltage for the unit (110) to fast variations of an envelope signal. This object is achieved by providing a second DC/DC converter (140) for generating a variety of n+1 voltage levels and n threshold values both in response to a received power control signal representing a required output power of the RF output signal and by a first DC/DC converter (130) to select one of said n+1 voltage levels as the supply voltage for said unit (110) in response to the result of a comparison between the envelope signaland said n threshold values.

摘要： A multiphase LC oscillator is proposed which belongs to the so-called class, which delivers correct-by-construction I/Q signals. Unlike state of the art I/Q LC oscillators, the proposed invention oscillates at the point where the quality factor of the resonator is maximum. Hence the new multiphase LC oscillator provides also maximum carrier to noise ratio correct by construction given a certain resonator. This is realized by implementing the V/I converters which couple the N LC oscillators, with an exact 180/N-degree phase shift.
