Abstract
Inventia se refera la domeniile tehnicii de masurare si radioelectronicii si poate fi utilizata pentru reproducerea rezistentelor negative virtuale cu reglare lina si bruta a valorii.Convertorul contine un amplificator operational (1) cu doua intrari si o iesire, doua cleme (2 si 7) de intrare, conectate respectiv la prima intrare a amplificatorului (1) si la masa, primul rezistor (3), conectat cu un pol la prima intrare a amplificatorului (1) si cu al doilea pol - la iesirea amplificatorului (1), precum si cel de-al doilea rezistor (4) variabil, conectat între cea de-a doua intrare a amplificatorului (1) si masa. Convertorul contine suplimentar un comutator (6), conectat cu contactul mobil la iesirea amplificatorului (1), si un bloc (5) din n rezistoare, conectate cu câte un pol împreuna la intrarea a doua a amplificatorului (1), iar cu polii liberi - respectiv, la contactele fixe ale comutatorului (6).
