isto tako stiga je i LT6202 u kojeg polažem velike nade s šumom od 1.9nV/√Hz , bit će potrebna mala modifikacija u WJ shunt regulatoru zbog ovog
The noise voltage of the LT6202/LT6203/LT6204 is equiva-lent to that of a 225Ω resistor, and for the lowest possible noise it is desirable to keep the source and feedback re-sistance at or below this value, i.e. RS + RG||RFB ≤ 225Ω. With RS + RG||RFB = 225Ω the total noise of the amplifier is: en = √(1.9nV)2+(1.9nV)2 = 2.7nV. Below this resis-tance value, the amplifier dominates the noise, but in the resistance region between 225Ω and approximately 10kΩ, the noise is dominated by the resistor thermal noise.
nabavljen je i BSP149 za novi strujni izvor za WJ shunt

, još jednom gosp. walt jung duboki naklon , mada je on dao ideju s LT6200 ,ali ništa lošiji nije ni LT6202
