phase error and amplitude error simulation

I am currently designing a single ended to differential converter. How can I performance the analysis for phase error and amplitude error?
Thank you.

hello, anyone can help to solve this problem? I need to see the phase error and the amplitude error of the output differential signal. Using cadence.

BASICALLY YOU NEED TO WRITE MEASUREMENT EQIATIONS TO FIND THE DIFFERNCE IN PHASE AND AMPLITUTE.

Phase diffence should be 180deg, so subtracting 180 deg and presenting the absolute value will give teh phase error.

absolute value of Amplitude difference is the amplitude error.
