Amplifier Current Noise Imaginary Impedance
Current Noise gets converted to voltage with Impedance so low impedance translates into lower effects of current noise.  U(f) = I(f) * Z(f)   ( or V=IR)
Thus devices with high current noise and low voltage noise (BJT's) are better suited to low Z designs. and low current noise (FETs) but with high voltage noise are better suited for high impedance and high voltage circuits.  See Ref*
