Abstract

U radu se prikazuje potpuno plivajući naponom kontrolisan otpornik (votage controlled resistor - VCR) sa negativnim otpornostima, sa širokim opsegom ulaznog napona. Bazira se na polovljenju ulaznog napona, uz korišćenje jednog spojnog tranzistora sa efektom polja (junction field effect transistor - JFET) u omskoj oblasti rada i naponom kontrolisanog strujnog izvora (voltage controlled current source - VCCS). Kontrolni parametar ovog strujnog izvora je ulazni napon kontrolisanog otpornika, a realizovan je korišćenjem strujnog prenosnika druge generacije (the second generation current conveyor - CCII) sa bipolarnim spojnim tranzistorima (bipolar junction transistors - BJTs). Performanse predloženog kontrolisanog otpornika simulirane su korišćenjem programskog paketa PSpice.
