Fully Integrated Switched-Capacitor PMU for IoT Nodes


Book Description

This book provides a step-by-step methodology and system design that can be used to design a fully integrated PMU using SC DC-DC converters, for any CMOS technology. The authors discuss trade-offs between power density and efficiency of the methodology for the 130 nm CMOS technology, and how to implement it on other CMOS technologies. The book describes the state-of-the-art of fully or near-fully integrated SC DC-DC converters with multiple conversion ratios and the techniques used to enhance the overall performance of these converters. Coverage includes the trade-off between the number of conversion ratios and overall extracted efficiency from a supercapacitor, as well as the sizing of the converter cells according to the desired output power and maximum clock frequency. The authors also describe in detail the design of the fundamental blocks for the converter operation, which includes a secondary control loop using capacitance modulation by sensing the clock frequency.

High-Ratio Voltage Conversion in CMOS for Efficient Mains-Connected Standby


Book Description

This book describes synergetic innovation opportunities offered by combining the field of power conversion with the field of integrated circuit (IC) design. The authors demonstrate how integrating circuits enables increased operation frequency, which can be exploited in power converters to reduce drastically the size of the discrete passive components. The authors introduce multiple power converter circuits, which are very compact as result of their high level of integration. First, the limits of high-power-density low-voltage monolithic switched-capacitor DC-DC conversion are investigated to enable on-chip power granularization. AC-DC conversion from the mains to a low voltage DC is discussed, enabling an efficient and compact, lower-power auxiliary power supply to take over the power delivery during the standby mode of mains-connected appliances, allowing the main power converter of these devices to be shut down fully.




Efficiency Enhanced DC-DC Converter Using Dynamic Inductor Control


Book Description

Omar Abu Mohareb proposes a novel dynamic inductor control (DIC) that can be generally applied to various DC‐DC converter types. The aim is to improve the converter efficiency throughout controlling the inductance value at all operating points without consequential complexity or increase in the inductor cost and size. The dynamic inductor control implies the maximum energy transfer (MET) concept to improve the DC‐DC converter efficiency and preserve a fast system dynamics against load changes at the same time. About the Author: Omar Abu Mohareb has earned his doctoral degree in Automotive Mechatronics Engineering from University of Stuttgart. He is now active in electromobility field and its efficient and smart infrastructure concepts. He has also earned his first patent on the proposed dynamic inductor control (DIC) concept.
