Now I have setup my circuit as follows. There is a current source at the base with step curent of 200mA and then a resistor of 1 G ohm is connected . So how do i measure for getting Ib vs Vbe curve . I am getting a linear curve having a slope of 1 when i run the probe for Ib vs V: Q1(b) (ie ) voltage across Base and emitter.
Since the Base emitter junction is acting like a diode it should give me a flat curve for voltage less than threshold voltage and then at the voltage when the diode turns on it should give a vertical straight line high current at that threshold voltage.
So can u advice where i am doing wrong or can u refer to someone who could help me out.
