Intel fourth-generation and fifth-generation Core microprocessors are powered by high-frequency integrated switching voltage regulators. The inductors required to implement these regulators are constructed using the routing layers of conventional organic flip chip packaging. This paper provides an overview of the construction of these inductors including representative results from production packages...
Intel® 4th generation Core™ microprocessors are powered by high frequency integrated switching voltage regulators. The inductors required to implement these regulators were constructed using the routing layers of conventional organic flip chip packaging. This paper provides an overview of the simulation and measurement of these embedded inductors including representative results from production packages.
Intel's® 4th generation Core™ microprocessors are powered by Fully Integrated Voltage Regulators (FIVR). These 140 MHz multi-phase buck regulators are integrated into the 22nm processor die, and feature up to 80 MHz unity gain bandwidth, non-magnetic package trace inductors and on-die MIM capacitors. FIVRs are highly configurable, allowing them to power a wide range of products from 3W fanless tablets...
