Hey everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to plot a straight line for a bipolar junction transistor to find the room temperature, T, using my experimental results for the associated base-emitter voltage, ##{V}_{BE}## and collector current, ##I_C##. Here's the equation that I'm using:

$$ I_C = α_F {I}_{EO} [exp(e{V}_{BE} / kT) - 1] + {I}_{CBO} $$

There is a few things that I'm unsure of though:

1. I assume that to create the straight line plot, I have to somehow take the logarithm of both sides and then convert it to the straight line equation, y = mx + c, however the issue is I'm not sure how to convert it and then deal with the extra terms.

2. I believe I have to assume some of the variables that I'm missing such as ##α_F## and ##{I}_{EO}##, I know ##α_F## to be the forward current transfer ratio, which for each I can estimate as 1. However I haven't a clue what to do with ##{I}_{EO}##, which I believe to be the reverse bias saturation current (not completely sure though).

I'll attach my results in excel, in case anybody wants to have a look.

Kind Regards,

Strides
