Po meni, to bi bilo pravo univerzalno rešenje!

Zbog strujnog šuma, verzija sa BJT nije primenjljiva za merenje THD pomoću elim. filtera jer ovaj poslednji ima relativno veliku izl. impedansu.
JFE2140 se baš lepo nudi za tu primenu - dva uparena JFET-a u SOIC-8 kućištu.
Možda još pogledati i Gronerov izvor konstantne struje, kod njegovog LNA to je najkomplikovaniji sklop.
Ako nedostaje literatura, tu sam da pomognem.

Čini mi se da je to i bila početna varijanta u ovoj temi...
