Hi Guys,
can anyone help explain why the ibis checker is reporting these huge
differences between the I-V curves and V-t curves. I checked the transient
response of the buffer and it looks good. Is it something to do with
tolerance or range of voltage?
Any help would be greatly appreciated.
Thanks,
Alaa Alani
here 's the ibis checker output:
