Abstract
A stacked pre-driver stage and a power amplifier including the stacked pre-driver stage are described. The stacked pre-driver stage comprises stacked pre-drivers arranged in series between a supply voltage and a reference voltage. Each pre-driver includes a pre-driving amplifier, together with MOS transistors. Each pre-driver is subject, in operation, to a voltage difference which is inferior to a maximum allowed use voltage of the MOS transistors with a largely reduced voltage drop across the regulator included in the power amplifier.
