SPICE simulations and circuit tests of digital noise reduction with MEMS inductors

Digital-noise reduction with decoupling capacitors in ever faster lower voltage technologies is gradually rendered ineffective by the line resistance to the capacitors. In contrast, blocking inductors show excellent noise reduction in SPICE simulations, the LdI/dt self-perturbance being solved with local auxiliary capacitors. The needed values for both inductances and capacitances are small, allowing their implementation in MCM (multi-chip module), or alternative, technologies. Circuit tests confirm the SPICE simulations
