PSU bio bio odradjen elegantno/prosto/jeftino sa dve alkalne baterijice 9V,
upotreba ovog LNA bila bi tako-i-tako povremena!

PSRR cijelog sklopa je oko -60dB @100Hz, ništa naročit, pogotovo uproščenim ulaznim diff.sklopom ispred opampova,
pa bi bio šum takvog napajanja sa 2x 9V alk.baterijicama kojeg je izmerio @Braca od oko 200pV/sqrt(Hz)

[Image: attachment.php?aid=42364]

i dodatnim komentarom, koliki je zapravo iz tog grafa effektivni šum baterijice
-> po oduzimanju pojačanja LNA od 60dB imamo svega 200pV/rtHz.

prisutan u signalu za više od konzervativno -40dB nižom umanjenim za PSRR,
pa bi bila njegova partecipacija u cijeloj priči od cca ispod 1pV/sqrt(Hz)... načisto zanemarivo!
