Abstract: An apparatus for amplifying an input signal is provided. The apparatus includes an output stage to generate an output signal. The apparatus further includes a compensation signal generator configured to generate a compensation signal based on at least one of a voltage value of the input signal or a voltage value of the output signal. The apparatus further includes a combiner configured to generate a control signal for the output stage based on a target signal, the compensation signal and a signal related to a current value of the output stage. The target signal corresponds to a desired output signal. The output stage is configured to generate the output signal using the control signal.

Abstract: An apparatus and a method for transmitting a signal over a wireless channel using a device including a polar transmitter joinable with a modulator are disclosed. For example, the method, by a circuit of the device, generates first and second streams of data from received data based on a type of modulator, a type of combiner and a channel frequency, each stream having at least some portion of the received data that is distinct from data included in the other stream, the type of combiner comprising a multiplicative or an additive combiner, the method, by the circuit, generates a first analog signal based on the first stream and generates a supply voltage based on the second stream, and the method by an amplifier coupled to the circuit, generates a Radio Frequency (RF) signal based on the supply voltage and the type of combiner.
