Abstract
A saturated power amplifier system has a saturated power amplifier that receives an input signal. The saturated power amplifier has one or more stages, including one or more output stages. Each output stage produces multiple signals which are combined. Each output stage has one or more levels of cascoding including one or more thick oxide devices and one or more thin oxide devices.
Claims44
A saturated power amplifier system, comprising:
- a saturated power amplifier that receives an input signal, the saturated power amplifier having one or more stages including one or more output stages, each of an output stage producing multiple signals which are combined, the output stage having one or more levels of cascoding, the cascoding including one or more thick oxide devices and one or more thin oxide devices, wherein a bias of cascoding devices is increased when a high output voltage is detected;
- a power supply coupled to the saturated power amplifier;
- and
- a source of positive feedback that is coupled to the one or more stages of the saturated power amplifier.
