I am doing a study in which i am checking how exposing a BJT to certain conditions like extreme temperature etc will permanently affect its characteristics.
But , the problem is how to check?
I thought that using a curve tracer would be good.
I could trace the curve for Vbe VS IB before and after the test.
I could also do similar tests for Hfe , Vce VS IC etc.
Perhaps that would give me the results.
I only have a scope and a few multimeters at my disposal to carry out the check. Can anyone give any ideas?
It would be interesting to build an addon circuit that will allow the scope to be used as a curve tracer also.
Can anyone tell me how?
How can i generate the sweeping voltage to drive the component to be checked?
And how can i convert the current that the component outputs into a voltage which can be seen on the scope?
Should i use a op amp?
