Single Ended To Differential Conversion

[arifsobhan]

i designed a differential gilbert cell for down conversion mixer from 2.4GHz to 100MHz and simulated in 130 nm CMOS in Mentor graphics. But the problem is i am not getting the code to determine the parameters in differential form. Can any one help me by getting this otherwise i need to convert my differential output to a single ended output.

Use a balun, I don't know Mentor but maybe they have predefined templates.

Thank you for your answer. But the problem is i want to avoid on-chip spiral inductor. I saw some balun circuits which are composed of inductors.

For example an LC-Balun. In the attached pdf are some examples.
