Abstract
A differential trace structure reducing the magnitude of low frequency attenuation is disclosed. The trace structure is formed on a printed circuit board. A pair of differential traces connects a signal receiver and a signal transmitter. A passive equalizer has a first shunt coupled to one of the pair of differential traces; and a second shunt coupled to the other one of the pair of differential traces. The passive equalizer has an inductor and a resistor coupled in series to the shunts. For low frequency signals, the passive equalizer behaves as a shunt resistance to the pair of differential traces.
