Distributed Matched Bypassing (2) • Elements: – Power-ground planes over (thin) laminate – A small number of SAME VALUE capacitors (2.2UF IDC) – Few bulk capacitors • Controlled-ESR capacitors • Smooth impedance profile • Suppresses plane resonances, and • Avoids antiresonances among – Capacitors, and – Capacitors and planes St.Cyr,Novak, Biunno, Howard ARIES 5 EPEP, October 2001

Distributed Matched Bypassing (3) • Conventional designs use C, ESR and ESL Resonances depend on all three >> – Hard to simulate all combinations – ESR for present capacitors cannot be specified • DMB relies on a user-defined series resistance (ABR) of bypass capacitors – Lowest number of capacitors – Straightforward positioning – C and ESL variations matter much less – Fewer combinations >> more predictable result – Components are equal >> increased reliability >> shared dissipation St.Cyr,Novak, Biunno, Howard ARIES 6 EPEP, October 2001

Conclusions • Smooth, optimum impedance profile is achieved by DMB (AVP, EAVP, DET) • DMB requires user-defined ESR • ABR is used to add series resistance to (ceramic) capacitors • ARIES implementation: • 130-180pH ESL • 1-1000MHz coverage St.Cyr,Novak, Biunno, Howard ARIES 13 EPEP, October 2001
