Abstract :
A broadband single-ended input differential output low noise amplifier exploiting IM2 cancelling has been designed in a 90 nm CMOS technology. A feedback path from the common mode output to the input effectively cancels the second order distortion products with negligible effect on the noise performance. The measured IIP2 varies from 17 dBm with the feedback disabled to 35 dBm when the feedback is enabled. Measured gain and noise figure are respectively 10 dB and 5 dB on a single output with 50 Omega load while dissipating 7.5 mW.
