Download or read book High Ratio Voltage Conversion in CMOS for Efficient Mains Connected Standby written by Hans Meyvaert and published by Springer. This book was released on 2016-05-24 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Advanced Multiphasing Switched Capacitor DC DC Converters written by Nicolas Butzen and published by Springer Nature. This book was released on 2020-07-03 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a detailed analysis of switched-capacitor DC-DC converters that are entirely integrated on a single chip and establishes that these converters are mainly limited by the large parasitic coupling, the low capacitor energy density, and the fact that switched-capacitor converter topologies only have a fixed voltage conversion ratio. The authors introduce the concept of Advanced Multiphasing as a way to circumvent these limitations by having multiple out-of-phase parallel converter cores interact with each other to minimize capacitor charging losses, leading to several techniques that demonstrate record efficiency and power-density, and even a fundamentally new type of switched-capacitor topology that has a continuously-scalable conversion ratio. Provides single-source reference to the recently-developed Advanced Multiphasing concept; Enables greatly improved performance and capabilities in fully integrated switched-capacitor converters; Enables readers to design DC-DC converters, where multiple converter cores are put in parallel and actively interact with each other over several phases to improve their capabilities.
Download or read book On chip Buck boost Switched capacitor DC DC Converter written by Chaohao Wang and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing integration level of CMOS integrated circuits (ICs) poses significant challenges for the power delivery network. Multiple independent power domains, each of them individually adjustable, are desirable for complex ICs to optimize the tradeoff between performance and energy consumption. A two-stage power management system, in which a first-stage global converter with a large down conversion ratio is followed by multiple second-stage local regulators for different power domains, fits well in modern power delivery networks. The first stage can be built with conventional, fully optimized DC-DC converters, while the second stage requires flexible, high-density, and high-efficiency on-chip DC-DC converters. With the enhanced fabrication capability of high-density on-chip capacitors, the switched-capacitor (SC) DC-DC converter becomes a perfect candidate for these second-stage on-chip regulators. This dissertation presents the architecture, modeling and design techniques for the development of fully integrated on-chip SC DC-DC converters for the purpose of local regulation. The proposed converter can step up or down the voltage based on the output requirement and circuit performance. Using the unit cell array approach, conversion ratios of n/(n+1) with buck configurations and (n+1)/n with boost configurations are achievable when n cells are grouped as a single converter. Thus, adequate topologies exist to provide a large range of output voltage with high efficiency. A prototype chip with 204 unit cells and nine different finely spaced buck and boost topologies was designed and fabricated in a 45nm bulk CMOS technology. The input is 1V, and the output ranges from 0.58V to 1.3V. The SC converter achieves a peak efficiency of 82.2% at a maximum power density of 0.16W/mm2. Furthermore, the efficiency varies by only 4.2% over the output voltage range. A digital algorithm for closed loop control was implemented in a field-programmable gate array (FPGA) to demonstrate that performance regulation using this type of converter can match circuit performance requirements and compensate for operating conditions or process variations. This dissertation also projects the potential improvements in SC converters with more advanced technology nodes as well as capacitor density scaling, such as using special on-chip capacitor processes like Metal-Insulator-Metal (MIM) capacitors and deep trench capacitors.
