Web19 sep. 1996 · However, for high frequencies the ground impedance is determined by the external inductance, and, ... shunt traces exhibits even a lower inductance than the … Web28 jan. 2024 · At a deeper level, your traces have some impedance, as they cannot be considered as long inductors. The board itself will affect the impedance of a circuit and your traces. The insulating PCB substrate creates parasitic capacitance, while the arrangement of traces and planes in interior layers creates parasitic capacitance and inductance.
