ABSTRACT:
Embodiments of a high-linearity low-noise amplifier (LNA) and method are generally described herein. Other embodiments may be described and claimed. In some embodiments, an RF input signal may be amplified with a cascode amplifier and a common-gate stage. The common-gate stage is dynamically biased based on an output voltage of the common-gate stage to allow an output voltage swing to be shared between the cascode amplifier and the common-gate stage.
