| Popis: | Presented in this paper are design considerations for a Monolithically Integrated Voltage Regulator (MIVR) targeting a 32mm2 multicore processor test chip taped-out in TSMC 28nm process. This is the first work discussing the utilization of on-die magnetic core inductors to support >50A of load current. 64 inductors with switching frequency of 140MHz are strategically grouped into eight interleaving phases to achieve 85% efficiency and minimize on-die voltage drop. |
