Patent abstract

A circuit and method are provided for reducing dynamic EVM of a power amplifier (PA) used for RF communication. A temperature dependent boost bias signal is applied to the bias input port of amplifier circuitry of the PA in dependence upon a temperature of the amplifier circuitry to compensate for transience in the gain or phase response of the PA while components of the PA is differentially warming-up, advantageously taking into account an actual temperature of the amplifier circuitry.
