An old discussion, about matching differential slew rates, had a suggestion of feeding
the differential signals into a heavy termination load, through a 1:1
transformer; it could just as easily (in that application) be called a common-mode filter,
except that you'd want it to PASS high frequencies, and some common-mode
filters are deliberately lossy.

Matching dI/dt amplitudes (but with one negative and one positive) into a resistive load
is one way to get symmetric dV/dt .
