description An exemplary embodiment of a low noise amplifier has integral noise cancellation to provide a low noise figure and operation over a frequency range of 40 GHz-60 GHz. An amplifier amplifies an input signal as well as noise present with the amplified signal and amplified noise being out of phase and in phase, respectively, with the corresponding inputs. An auxiliary amplifier amplifies the same inputs and generates an amplified signal and amplified noise both being out of phase relative to the inputs. A summation circuit combines all of these amplified signals with the noise being cancelled since the auxiliary amplifier provides the same amount of amplification as the amplifier and the amplified noise signals being summed are 180 degrees out of phase to each other. Preferably, the amplifier, auxiliary amplifier and the summation device utilize CMOS transistors disposed on an SOI substrate with impedance stabilization over the frequency range.
