Abstract:
A single-stage amplifier circuit includes first and second transistors (e.g., BJTs or FETs) connected in parallel between the amplifier's input and output nodes. The first and second transistors are configured differently using known fabrication techniques such that a (first) cutoff frequency of the first transistor is at least 1.5 times greater than a (second) cutoff frequency of the second transistor, and such that a ratio of the respective cutoff frequencies produces a significant cancellation of second derivative transconductance (Gm″) in the amplifier output signal, whereby the amplifier achieves significantly improved IIP 3 . Alternatively, the amplifier is configured using MOSFETs having respective different channel lengths to achieve the desired cutoff frequency ratio. An exemplary communication circuit includes a low-noise amplifier having two NPN BJTs that are fabricated using different collector doping concentrations, different emitter doping concentrations, or different base region widths in order to achieve the desired cutoff frequency ratio.

Claim (Index 18):
The amplifier circuit of  claim 14 , further comprising means for applying a bias voltage onto at least one of the first base region of the first BJT, the first emitter region of the first BJT, the second base region of the second BJT, and the second emitter region of the second BJT.
