Dear guys,
 I want to design a high speed single to differential buffer, here my input is 2GHz rail-to-rail,
and the convertor needs to be design for low noise application, harmonics of output differential signal does not care very much.
 any suggestion is welcome.

hi
i think you can pass the signal to a inverter and a cmos pass-gate repectively, and reform the waves again by inverters.
the other method is pass the original to a diff-amp with resistors load, and the other input is 1/2 vdd.
hope this help.
