Abstract

Inventia se refera la un amplificator de putere în clasa BC, format dintr-un preamplificator, un preamplificator intermediar si amplificator final, în contratimp, simetrice, echipat cu tranzistoare cu parametri identici si conductivitate inversa, realizat pe doua ramuri ce lucreaza în clasa B, continînd cel putin un etaj amplificator în clasa C. Amplificatorul, conform inventiei, prezinta volum si o greutate mica, un cost redus si o tensiune mare de iesire, raportata la tensiunea de alimentare.Inventia foloseste un singur etaj de alimentare simetric (+E, -E), evitîndu-se utilizarea unor surse de alimentare complicate si scumpe.
