Abstract : For conventional RF power amplifier (PA), the power efficiency depends on the peak to average power ratio (PAPR) of the input signal, or more precisely on the statistical distribution of the input signal amplitude. In this paper, we show that, in a similar way, the power efficiency of switching mode PA driven by ΣΔ or PWM signals depends on the statistical distribution of input signal the states and on a parameter equal to the Peak to Average Duration Ratio. This parameter is related to the PAPR in a way depending on the type of encoding of PA input signals
