Abstract:

A 16-core voltage-stacked IC integrated with a switched-capacitor DC-DC converter demonstrates efficient power delivery. To overcome inter-layer voltage noise issues, the test chip implements and evaluates the benefits of self-timed clocking and clock-phase interleaving. The integrated converter offers minimum voltage guarantees and further reduces voltage noise.
