Abstract
Briefly, in accordance with one or more embodiments, in a pulse position and pulse position modulation out-phasing transmitter, the range of the phase angle, theta, may be divided into more than one range to drive a first power amplifier with a first range of theta, and to drive a second power amplifier with a second range of theta. In one or more embodiments, a main power amplifier is driven with a first phase range having a higher probability density function, and an overload power amplifier is driven with a first phase range having a lower probability density function. In one or more embodiments, a full adder may be used to combine the two phases wherein the sum signal is used to drive the main power amplifier, and the carry signal is used to drive the overload power amplifier.
