1 Return Paths and Power Supply Decoupling Dr. José Ernesto Rayas Sánchez 1 Outline Ideal return paths Microstrip return paths Stripline return paths Modeling metallic reference planes Power supply bypassing Ground bounce and SSN 2

2 Ideal Return Path 3 Return Path with a Discontinuity 4

3 Discontinuity in the Signal Path 5 Microstrip Return Path 6

4 Stripline Return Path (Off Steady State) 7 Stripline Return Path (Turn On) 8

5 Stripline Return Path (Turn Off) 9 Stripline with Unrelated Power Plane (Turn On) 10

6 Return Paths The return paths in microstrips are very different to those in striplines For striplines, the current distribution in the two reference metallic planes can be very different Usually, the return path is considered as an ideal short circuit. However, any parasitic inductance in the return paths can significantly affect the signal integrity in both the return paths (metallic planes) and the signal trace 11 Modeling the Metallic Reference Planes w C plane l L plane metallic planes ε r C R plane R plane plane lw ε rε o h l ρ tw h L plane µ rµ o hl w 12

7 Using Decoupling Capacitors Ideally, the metallic reference planes should be pure short circuits at the signal frequency range The metallic reference planes essentially behave as capacitors Decoupling capacitors are used to lower the metallic planes impedance at the frequency of interest 13 Using Decoupling Capacitors Example 14

8 Using Decoupling Capacitors Example (cont) 15 Power Supply Inductance 16

9 Ground Bounce Ground bounce refers to a change in the reference voltage caused by switching currents in the return paths It is also called Simultaneous Switching Noise (SSN) or Delta-I Noise It is mainly produced by the parasitic inductance in the return path The problem gets worse in digital systems when many drivers are switching simultaneously 17
