The circuit of transistor characteristic curve depicting instrument

Published:2011/6/5 22:04:00 Author:Seven | Keyword: transistor characteristic curve, depicting instrument | From:SeekIC

See as figure (a), the circuit consists of a sawtooth wave generator and a step wave generator. As depicting transistor characteristics needs two voltages, one the them is the step wave on b pole, by which a basic pole current is generated; the other is the sawtooth wave on C pole. The period is corresponding to the step wave, so that the output characteristic curve of the transistor can be depicted, i.e the characteristic curve of Ic-Vce. The sawtooth wave generator consists of the multi-resonate oscillator (IC(555),R1,R2 and C1) and the integration circuit(C2 and R3).
