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. The NF equation needs to include ...
Linear Integrated Systems announced the LSK489, an N-channel monolithic dual JFET with 1.8 nV per square root Hz noise at 1kHz and low-capacitance (Ciss= 4pF) . This lower capacitance will greatly ...
