Abstract
Techniques are described herein that adaptively suppress harmonic distortion in an amplifier utilizing negative gain. The amplifier includes a first amplifier stage and a second amplifier stage, which are coupled in parallel. The first amplifier stage has a positive gain. The second amplifier stage has a negative gain to suppress total harmonic distortion of a system that includes the amplifier. The amplifier further includes shunt-peaking circuitry coupled to the first amplifier stage and the second amplifier stage to increase a maximum operating frequency at which the amplifier is capable of operating.
