IB[μA]
Politechnika Częstochowska
Laboratorium Elektroniki
Temat: Tranzystory bipolarny i unipolarny.
1. Cel ćwiczenia.
Celem ćwiczenia jest zapoznanie się z własnościami i charakterystykami tranzystora bipolarnego npn oraz tranzystora unipolarnego z kanałem typu n.
2. Układy pomiarowe.
a) układ pomiarowy do zdejmowania charakterystyk tranzystora bipolarnego
b) układ pomiarowy do zdejmowania charakterystyk tranzystora unipolarnego
3. Tabele pomiarowe.
a) charakterystyka IB=f(UBE)
dla UCE=6V
