Abstract: Techniques are disclosed to instruct how a switched capacitor digital power amplifier (PA) is configured to operate using high supply voltage levels beyond twice the maximum voltage rating for any of the transistor terminals such as Vds/Vdg/Vsg. The digital PA has a topology that comprises a dual-feedback capacitive path that comprises a capacitive divider and a voltage stabilizing feedback path to selectively couple the capacitive divider to DC bias voltages.

Abstract: For example, an apparatus may include an input to receive an input signal in a first voltage domain; a multi-mode power amplifier switchable between a plurality of power modes to generate an output signal based on the input signal; and an output to provide the output signal. For example, the multi-mode power amplifier may be configured to provide the output signal in the first voltage domain at a first power mode, and to provide the output signal in a second voltage domain at a second power mode. For example, a maximal voltage of the second voltage domain may be at least two times a maximal voltage of the first voltage domain.
