Original Abstract Submitted
Distortion correction for fast supply voltage changes in a power amplifier is disclosed. In one aspect, analog predistortion in the power amplifier to maintain linearity of the power amplifier is based on a supply voltage, thereby avoiding a need to write into registers. Further, the supply voltage with its changes may be used to set the predistortion levels both for amplitude and phase. By using the supply voltage, long signals writing to registers in the power amplifier or power management circuit may be avoided, resulting in faster application of predistortion. The faster application of the predistortion works nicely with symbol or even sub-symbol adjustments to the supply voltage resulting in greater efficiency in the power amplifier.
