I need help identifying some TO-92 components.
I asked for some BSS138 or 2N7000 mosfets at a local component shop yesterday, What i received was this:
- TO-92 package
- front is painted in metallic blue
- center leg is offset to back
- markings are:

You must have 3 columns: Input/Output and time.
Having those 3 columns, MATLAB is able to find a transfer function that models your circuit with its toolbox called System identification Toolbox.

Yes, that is correct but there may be a more fundamental problem here.
You are asking for Caller identification, the designs so far are DTMF decoders, if you are looking to find out where a call originated from (the callers number via landline), a different protocol is used and it is also different from one Telco to another.

I'm not 100% sure as I currently don't have access to documents of 65nm, but there may be cases where they needed DRC tool to know which diffusion is the drain. So they may have added it for this reason. For example an extended drain or a lightly doped drain device may have different rules which requires identification of the drain. Otherwise most
