Hello all:
does anyone know a good criteria or standardized method to select the start and end points(values) of the Conduction Region in a I-V curve for a pn Juction Diode.
it is required to perform a linear fitting straight line between the points and extract the Threshold Voltage (also called Cut in) from the diode.
If someone can help, I'm attaching one of my curves.
The reason of my request is to be able to follow always a same methodology for all my curves. Regardless of the value of the Threshold Voltage and how far the Breakdown point to the Forward Bias might be.
Regards ! :)
Dear Franklin Uriel Parás Hernández,
I propose a method for intersecting straight segments in double logarithmic coordinates, or find the extremum of the second derivative in the same coordinates.
10^(-0.24)=0.57544 (see figure)
Best regards.
Dear Alexander:
Thank you for your reply,
I will try to review one of these two methods
Can you share the source ? where are these reported?
Regards !
