Hi, In many receiver(CMOS/TTL level output)product, it gives the spec of the output high voltage(Voh) as below; ......... Voh 3.8V-typ 4.9V-max
the test condition above is Ioh=2mA,Vid=+200mv ........... I drafted the testbench for the above as attached diagram.
I want to know if the current source in th ediagram is used in the test. Someone told me it is replaced by the resistor.
And also, if I want to deisgn a receiver chip, in the design, how can I simulate this spec?Used an ideal current source?
Thanks
