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. Measured inductors reported in this paper span from 1 to 6.7 nH under 2.4 mm2 and achieve $Q$ of up to 24 at 140 MHz (the switching frequency). [ABSTRACT FROM AUTHOR]

This paper presents thin-film high-rejection bandpass filters integrated into organic substrate technology called RXP. A circuit topology based on unique resonator and grounding inductor is proposed. The proposed circuit provides design freedom of locating transmission zeros at lower and upper stopbands relative to the center frequency. About 2.4 GHz narrow band (<200∼MHz) and 5 GHz wide band (>1∼GHz) bandpass filters have been implemented in four-metal layer with 0.191 mm thin RXP substrate. The measured results show good agreement with simulations. [ABSTRACT FROM AUTHOR]
