Accurately predict measured noise figures for transformer coupled differential amplifiers (Part 2 of 2)

Using a transformer-coupled differential inverting amplifier stage can give a very low input referred noise voltage or Noise Figure (NF) with exceptional SFDR/mW of power. Modern FDA’s can deliver ...
