LNA 60dB D100
(01-15-2025, 07:59 AM)Dragan100 Wrote: Odlično, hvala za merne rezultate, 
video sam več u simulaciji sa single OPA1655 da sa izlazima 1Vpeak i 2Vpeak ima još uvijek odličan THD sa tih 500R NFB.
Pošto su  single OPA1655 SOT-23-5  i dual OPA1656 SOIC-8 smešnih cena, mogu simulirati sa dual opampom,
drugi opamp da ganja NFB, pa da vidim razliku/tendencu opadanja (ako uopšte) THDja.

Simulacijski sam odradio ULNA D100 JFE2140 modul sa Dual opampom OPA1656, pridobije se nekih 2dB II.harm, 2,5dB III.har., ostali viši harm. od 2,5...3dB 
Slično se je moj SIM pokazao mernim rezultatima koje je Braca postavio, 
vidi ispod kolonu sa 493R5 1V i 2V, opterečenja 2mA i 4mA, slično slabljenje II. i III.harm.
