    Abstract: Circuitry that includes a radio frequency (RF) power amplifier (PA) and a dynamic supply boosting circuit, is disclosed. The RF PA receives and amplifies an RF input signal to provide an RF transmit signal using a PA power supply voltage. The dynamic supply boosting circuit provides the PA power supply voltage using a dynamic supply input voltage, wherein when a peak-to-average (PAR) of the RF input signal exceeds a PAR threshold, the dynamic supply boosting circuit boosts the PA power supply voltage, such that the PA power supply voltage is greater than the dynamic supply input voltage.
