Integrated voltage regulators (IVRs) are considered nowadays as major elements in the development of power delivery networks for digital electronics because of their ability to implement point-of-load voltage regulation in multicore microprocessors and system-on-chip (SoC) architectures. Inductive regulators generally enable higher power efficiency over a wide range of conversion voltages. However,...
This paper demonstrates a new approach to model the impact of thermal effects on the efficiency of integrated voltage regulators (IVRs) by combining analytical efficiency evaluations with coupled electrical and thermal simulations. An application of the approach shows that a system-in-package solution avoids thermal problems typically observed in other IVR designs. While the evaluation in this paper...
Integrated voltage regulators (IVRs) are one of the main trends in power delivery networks (PDNs) for electronic systems. A major challenge in the IVR design is to achieve sufficient integration / minimization of the required passive components of the IVR while still maintaining high power efficiency. This paper demonstrates that a buck converter type IVR designed with package embedded magnetic core...
Low-cost and compact size is endlessly requested by new wireless and mobile communication systems. These requirements are critical for some specific application such as bandpass filter(BPF). Most of today embedded filters in SIP are made on low temperature co-fired ceramics (LTCC) technology, which eliminates Surface Mount Technology (SMT) and reduces the size of the filter. While LTCC filter can...
