The invention provides an improved differential output structure with
minimal skew and introduces less process variations. According to one
embodiment of the invention, a differential output structure is provided
and comprises an input line, an output driver and a sync circuit. The
input line includes first and second paths. The first path has an input
end for receiving input signals. The first path also has an output end and
includes at least one driving element. The second path has an input end
operably coupled to the input end of the first path for receiving the
input signals. The second path also has an output end. The output driver
is operably coupled to the output ends of the first and second paths and
is configured to provide differential outputs. The sync circuit is
operably coupled between the first and second paths and is configured to
synchronize the speed of signals traveling on the two paths.
