In this paper, a CMOS switched-capacitor voltage doubler is proposed. It employs the techniques of clock synchronization and charge transfer blocking to minimize the reversion loss. The clock transition period detection and boosting circuit modules allow continuous charge action to the output node, which significantly improves operation performances. The proposed voltage doubler was designed using IBM 180 nm CMOS process, with a 1.2 V supply voltage. Under no-load condition, it achieves 99.92% of ideal voltage level with 8 mV voltage ripple, while consuming only 9.6 ¿W of quiescent power. With a load ranging from 20 k¿ to 200 k¿, the up-conversion ratio performs 45% better than the prior arts.

system-on-Chip solid state circuits that sense, receive, transmit, and process signals are the sensors, or eyes and ears, of the medical field of the millennium. The goal and design of the system-on-Chip (SOC) program for industry will be to provide affordable, reproducible, and reliable front-end instrumentation, components and subsystems for medical systems. To process/store/analyze the signals acquired from these medical sensors, analog/digital systems are used to provide data fusion and information extraction. These biomedical smart sensors cover the hybrid domains of mixed-technology (electrical, mechanical, optical, thermal, biochemical) and mixed-concept (electrical, control, digital signal processing). These significant domain design differences impose robust design challenges for medical sensor technology.

A hierarchical approach for the abstraction of digital VLSICs is presented. Circuit layout is hierarchically abstracted into logical constructs of binary tree structures, which may be manipulated to extract circuit functionality for the purpose of verifying design correctness. VLSIC design specification in the form of HDL is hierarchically decomposed to generate logical formulae for the given specification. By comparing the above, a verification report is obtained

A new differential input CMOS transconductor circuit for VHF filtering application is introduced. The new circuit has a very high frequency bandwidth, large linear differential mode input range and good common mode signal rejection capability. Using 0.35 /spl mu/m CMOS technology with 3 V power supply, the transconductor has a 0.9 V linear differential input range with a -54.6dB total harmonic distortion (THD) and more than 1 GHz - 3dB bandwidth. A 3rd order elliptic low pass g/sub m/-C filter with a cutoff frequency of 150MHz is demonstrated as an application of the new transconductor.

The goal of the SMART4ALL EU funded project is to build capacity amongst European stakeholders via the development of self-sustained, cross-border experiments that transfer knowledge and technology between academia and industry. It targets Customized Low Energy Computing (CLEC) in the Cyber-Physical (CPS) and the Internet of Things (IoT) domains by combining a set of unique characteristics that join together different cultures, different policies, different geographical areas, and different application domains. The SMART4ALL vision will be realized mainly through funded (via open calls) Pathfinder Application Experiments (PAEs) that will enable the transformation of academic knowledge into industry especially targeting South and Eastern European countries that are currently underrepresented in European funding opportunities. In this way community building, strategy development, and ecosystem learning are envisioned for boosting high-quality research and development in South Eastern Europe (SEE), through an efficient combination of regional, national and European policies. Furthermore SMART4ALL sets forward the concept of marketplace which is offered as a service (Marketplace-as-a-Service or MaaS) that acts as one-stop-smart-stop by offering tools, services, platforms based mainly on open sources technologies as well as technology suppliers - adopter matchmaking capabilities customized to the targeted thematic pillars of the project.

With the evolution of mobile devices and networks, and the growing trend of mobile Internet access, rich, multi-player gaming using mobile devices, similar to PC-based Internet games, has tremendous potential and interest. However, the current client-server architecture for PC-based Internet games, where most of the storage and computational burden of the game lies with the client device, does not work with mobile devices, constraining mobile gaming to either downloadable, single player games, or very light non-interactive versions of the rich multi-player Internet games. In this paper, we study a cloud server based approach, termed Cloud Mobile Gaming (CMG), where the burden of executing the gaming engines is put on cloud servers, and the mobile devices just communicate the users' gaming commands to the servers. We analyze the factors affecting the quality of user experience using the CMG approach, including the game genres, video encoding factors, and the conditions of the wireless network. Based on the above analysis, we develop a model for Mobile Gaming User Experience (MGUE), and develop a prototype for real-time measurement of MGUE that can be used in real networks. We validate MGUE model using controlled subjective testing, and then use it to characterize user experience achievable using the CMG approach in wireless networks.
