Abstract :
The signal propagating along a microstrip line over a slot on the power plane will suffer from composite effects of reflected noise by a discontinuity in the signal return path and ground bounce between power/ground planes. The paper investigates noise reduction by using differential signaling. An efficient 2D FDTD method, together with equivalent circuits for the differential line and the slot, is established and simulations are performed for a three-layer structure to characterize ground bounce coupling.
