Abstract
An amplifier for operating at low, middle or high linearity modes, the amplifier comprising a first low noise amplifier (LNA) coupled to a second low noise amplifier for providing amplification; a first degeneration inductor coupled to the first LNA for providing impedance matching; a −ggeneration block coupled to an output of the second LNA for canceling third-order transconductance distortion; and a first enabling/disabling component coupled to the output of the second LNA and aligned in parallel with the −ggeneration block for operating at least one of the first and second LNAs at one of the low, middle or high linearity modes.
