Abstract
Embodiments of a high-linearity low-noise amplifier (LNA) 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. The cascode amplifier may include integrated notch filters to attenuate undesired signals. The cascode amplifier may operate from a large power supply when blockers are present to avoid voltage swing compression at its output. The cascode amplifier may be biased and designed to operate in a class AB mode to produce linear output current to avoid current compression or excessive current expansion.
