I have a cabel model for Spectre in form of an S parameter file. Interestingly, it inverts at DC but not at higher frequencies. The lowest frequency tabulated in the file is 10MHz. Another interesting behavior is that if I feed into the line a DC unbalanced pattern (average = 20mV), out comes a DC balanced one. Why?
What I am after is, whether my cable amplifies the DCD from the input to the output.
What am I missing here? How realistic is the shown transient response, if the DC response is clearly wrong?
