LTSpice - OpAmps
#1
Nekon malo igranja sa operacionim pojacivacima, evo par common dizajna iz mog procesa ucenja o njima pa ako jos nekom pocetniku treba, da moze da se poigra, a vi iskusniji ispravite ako sam nesto negde opasno omasio.

Imena su self-explanatory tako da mislim da nema potrebe komentarisati ih.

Op-Amp kao voltage comparator:

Non-Inverting Amplifier:

Voltage Follower:

Sto se tice voltage-follower-a, nisam siguran gde se tacno primenjuje u praksi, te bih zamolio nekog iskusnijeg da pojasni na prostom primeru ako je moguce.

Dodacu jos neke konfiguracije kasnije, pa onda krecem da vas gnjavim sa pitanjima Smile

A u prilogu evo ovih trenutnih ASC fajlova za LTSpice.
