Original Abstract Submitted
this disclosure is directed to an amplifier with improved linearity compared to other amplifiers. the amplifier may include auxiliary active circuitry to reduce amplitude and/or phase non-linearity of a single-ended or differential common-source amplifier when generating amplified signals. as such, the amplifier may output the amplified signals having an output power across a range of output powers with improved linearity. for example, the amplifier may output the amplified signals with improved linearity when operating at a normal power mode and a power back-off mode. the auxiliary active circuitry may include common-gate amplifiers cross coupled with the common-source amplifiers.
