  • 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

ARIES 6

EPEP, October 2001

  • 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

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
