Building the behavioral model for each analog circuit is an efficient approach for mixed-signal system verification. If an automatic model generator is available, it is useful for designers to reduce the extra efforts. Instead of modeling the relationship between circuit inputs and outputs directly, a divide and conquer approach is proposed in [8] to divide the circuit into several small building...
The support of two-way flow of information and electricity in smart grid enables the effective use of market-based mechanisms which promises to ensure fair and efficient resource allocation and, at the same time, provide economical and reliable electricity services to power consumers. In this next-generation power grid, a variety of energy management challenges such as balancing the demand and supply,...
In this letter, a microwave annealing (MWA) method for Ohmic contact applied to InAlN/GaN high electron mobility transistor (HEMT) is the first time. The feature of MWA method is low operating temperature (450°C∼550°C). By using this technique, MWA-HEMT can achieve a low Ohmic contact resistance and smoother Ohmic contact surface than traditional rapid thermal annealing (RTA). The situation of Indium...
We investigate the wideband response of a non-Foster element based on a radio frequency operational amplifier. Our results indicate that the input impedance of a non-Foster element co-existing with a stabilization network exhibit an inverted Lorentzian resonance. This makes its full-range frequency response satisfy the Kramers-Kronig relations. In this case, while the conventional non-Foster response...
The detection performance analysis of ship radar under interference environment are presented. The signal detection model of ship radar is constructed to analyze the detection performance. The sea clutter generation models are constructed to simulate the sea clutter's influence. And the interference models are constructed as well. Based on these models the false alarm rate and the detection threshold...
We construct a two-port non-Foster element with an unconventional use of a floating negative impedance convertor. Compared with one-port non-Foster elements, it is able to have a non-Foster transmission coefficient that can be used to compensate distortion of input signals due to nonlinear frequency response of Foster networks. Both theoretical and simulated analysis verified the effectiveness of...
In this study, we investigate the group delay distortion of a signal due to the presence of dispersion in transmission systems, and propose an approach to eliminate the distortion by dispersion compensation based on engineered material dispersion. We demonstrate that utilizing the anomalous frequency response of a dispersive material, envelope distortion of a signal passing through a given transmission...
The field strength correction mechanism of radiation fields of phased array antennas solving by the approximate superposition method is analyzed. When approximate superposition method is used to achieve radiation fields of phased array antennas accurately, the fields must be corrected according to the power. The field strength correction coefficients depend on the array elements numbers, interval...
A high-gain flip-chip packaged dielectric resonator antenna (DRA) for THz imaging applications is proposed in this work. The THz DRA is composed of a high-resistivity silicon dielectric resonator fabricated in an integrated-passive-devices (IPD) technology and a feeding patch realized on a 0.18-μm CMOS chip. The DR is flipped and thermo-compressively bonded to the chip by gold microbumps. With a 625-μm...
This paper presents the results of the depth estimation challenge for dense light fields, which took place at the second workshop on Light Fields for Computer Vision (LF4CV) in conjunction with CVPR 2017. The challenge consisted of submission to a recent benchmark [7], which allows a thorough performance analysis. While individual results are readily available on the benchmark web page http://www...
The capacity region of 1-to-K broadcast packet erasure channels with ACK/NACK is known for some scenarios, e.g., K ≤ 3, etc. However, existing achievability schemes either require knowing the target rate R in advance, and/or have a complicated description of the achievable rate region that is difficult prove whether it matches the capacity or not. This work proposes a new network coding protocol with...
In this paper, a self-constructing fuzzy wavelet neural network (SFWNN) is used to approximate an unknown nonlinear term in the system dynamics with the structure and parameter learning abilities concurrently. Further, a self-constructing fuzzy wavelet neural control (SFWNC) system, which is composed of a computation controller and a robust compensator, is proposed. The computation controller using...
Since traffic engineering (TE) in Software Defined Networking (SDN) can be much more efficiently and intelligently implemented, Multipath in SDN becomes a new option. However, Ternary Content Addressable Memory (TCAM) size become the bottleneck of SDN. In this paper, we propose an SDN-based Dynamic Flowentry-Saving Multipath (DFSM) mechanism for inter-DC WAN traffic forwarding. DFSM adopts source-destination-based...
Fall incidents are one of the most important ward safety issues in hospitals because falls may cause extreme injuries, resulting in serious physical, psychological, and social consequences. In this paper, we present a smart ward with a fall detection system. The smart ward can issue an alarm signal to corresponding healthcare givers once it detects a fall event. The smart ward is consisted of a Kinect...
We propose a new cloud gaming platform to address the limitations of the existing ones. We study the rendering pipeline of 2D planar maps, and convert it into the server and client pipelines. While doing so naturally gives us a distributed rendering platform, compressing 2D planar maps for transmission has never been studied in the literature. In this paper, we propose a compression component for...
Data centers concern not just energy usage, but also other important overall considerations such as the actual computational work, the energy efficiency and the performance of servers. The server, as one of the key ingredients of a data center, plays an increasingly crucial role in contributing to the overall energy use, especially in cases where the efficiency of the infrastructure has been optimized...
This work demonstrates the isolation integrity between gate contact and source or drain contact with the variety of source/drain extension lengths. The trend of isolation capability not only linearly followed the extension length, but related to the formation of liner spacer. As the channel width (Wfin=0.11μm) was fixed, the IGD leakage at channel lengths Lg= 0.24, 0.16, and 10μm with LSDE= 160nm...
Fixing the doping dosage in VT implant process, as the doping energy is lower; contributing the good p-n junction controllability, the punch-through voltage (VPT) at 6keV doping energy is greater than that at 10keV, no matter what the long-channel devices are. This phenomenon is similar to the trend of the DIBL values for channel width = 0.12μm at 10keV are slightly larger than that at 6keV, too.
The DIBL effect is well-known in short-channel devices. Using this good effect, we can detect the device integrity with channel-length or -width variation and the channel punch-through effect, causing more leakage contributing the OFF current. As the channel width is increased at the long-channel lengths, the punch-through voltage (VPT) is also increased little due to the more uniformity of halo implantation...
One interesting result for 28nm high-k stacked n-channel MOSFET with W/L= 0.5/0.12 (μm/μm) electrically sensed demonstrates the tunneling and GIDL effects which can effectively be decoupled by gate bias at accumulation mode. Due to the drain bias assisted, the decoupling performance in this work is more apparent. In the low gate bias, the GIDL effect is clearer; reversely, the tunneling effect is...
