    Abstract: An outphasing amplifier includes a first class-E power amplifier having an output coupled to a first conductor and an input receiving a first RF drive signal. A first reactive element is coupled between the first conductor and a second conductor. A second reactive element is coupled between the second conductor and a third conductor. A second class-E power amplifier includes an output coupled to a fourth conductor and an input coupled to a second RF drive signal, a third reactive element coupled between the second and fourth conductors. Outputs of the first and second power amplifiers are combined by the first, second and third reactive elements to produce an output current in a load. An efficiency enhancement circuit is coupled between the first and fourth conductors to improve power efficiency at back-off power levels. Power enhancement circuits are coupled to the first and fourth conductors, respectively.

    Abstract: A method of canceling nonlinear distortions in pulse width modulated signals includes receiving an input signal. A first signal that is the modulated input signal is generated. The first signal has quantized levels representing the input signal. A pulse width modulated (PWM) sequence that is representative of the first signal is generated. A second signal that is the PWM sequence mixed with a carrier signal is generated. An error signal is generated in response to the first signal and modeled from the second signal. The error signal is added to the input signal.

    Abstract: For generating quantized signals, a quantized phase domain related to quantized phases of an input signal is generated. Vectors that the input signal may occupy are calculated based on the quantized phase domain. A first quantized phase of a first component of the input signal is generated per the quantized phase domain, and a second quantized phase of a second component of the input signal is generated per the quantized phase domain.
