Distribution Fault outage directly influences the normal electricity consumption. Accurate evaluation of distribution fault outage cost plays a key role in the investment and decision on improving the power supply reliability. Based on distribution topology, we first analyze the characteristics of distribution load when take distributed photovoltaic generation (DPG) into accounts and propose the practical...
A user association algorithm is proposed for energy consumption and traffic load balancing tradeoffs among heterogeneous base stations in heterogeneous networks with renewable energy supply. The concept of topology potential is introduced to represent the attraction between base stations and users, which takes the traffic load of users and the available renewable energy of base stations into consideration...
The rapid development of cloud computing stimulates many research works on Data Center Networks (DCNs), among which studies on energy consumption account a considerable proportion. However, a generic simulation tool that is flexible and user-friendly for such studies is still unavailable, which hinders the research in this area as it is impractical for each research group to build a DCN testbed for...
Cluster management has become a multi objective task that involves many disciplines like power optimization, fault tolerance, dependability and online system operation analysis. Efficient and secure operation of these clusters is a key objective of any data center policy. In addition, the service provided by these servers must fulfill a level of quality of service (QoS) to the customers. Applying...
This paper describes a design flow for the circuit-level optimization of a technology. The concurrent exploration of device characteristics and library design choices leads to a more application-optimal technology. We illustrate the design flow by: 1) analyzing the impact of buffer cell design, and 2) by optimizing a 130 nm technology for low operational power.
This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
A novel compact coupled planar resonator (CCPR) based VCO (voltage controlled oscillator) using mode-coupling technique was developed in response to expensive high Ceramic and SAW resonators based signal source for wireless communications. One of the problems related to the conventional Ceramic/SAW based resonators (with high Q and low phase noise) is the challenge for integration in IC form. Instead...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
