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: A transistor device can include a drain contact operably connected to a drain finger and a source contact operably connected to a source finger. The transistor device can further include diffusion area connected to the drain finger and the source finger to provide current to the drain finger and the source finger. The drain finger can have a length extending along an axis and different drain finger widths along the drain finger length such that current density is equal at each point along the drain finger length. The source finger can have a length extending along the axis and source finger widths along the source finger length such that current density is equal at each point along the source finger length.

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.
