A new technique of employing gate like metallic structure on the ground plane to achieve enhanced gain and stable radiation pattern of an ultra-wideband (UWB) microstrip line fed planar monopole antenna is proposed. Two antennas with rectangular and semicircular gate like structures are designed having impedance bandwidth from 2 GHz to more than 11 GHz. The realized gain of the proposed antennas are...
As CMOS scales further into non-CMOS technology, being able to measure reliability of modern logic integrated circuits instantly and correctly is fast becoming necessary. Therefore, reliability assessment has become a decisive step in the design methodology of nano-sized circuit systems. In contemporary to current literature, the existing reliability assessment tool based on Probabilistic Gate Model...
As CMOS technology advances to nano-scale devices, the performance of logic integrated circuits becomes a focal point in current literatures. The circuit's performance measured based on its reliability is not only depending on its gate error probability, p, but it also depends on the architecture of that circuit. Thus, this drives a need to measure and evaluate reliability values for different architectures...
As digital logic circuit are being fabricated at nanometer scale, the reliability of the circuit becomes an important issue. Therefore the reliability modeling is increasingly important subject to be considered in designing modern logic integrated circuits at submicron level. This drives a need to compute reliability measure for nano-scale circuits. Two main reliability measuring tools used commonly...
Because of its wide bandgap, silicon carbide is attractive for applications in harsh environments, especially high temperature applications. Thermal generation currents are negligible in SiC, even at high temperatures, and the intrinsic temperature of SiC is above 900??C. As a result, the upper temperature of SiC devices is limited by the stability of the associated metallurgy or dielectrics, rather...
A LoWPAN is a communication network that allows wireless connectivity in varies applications due to its unique advantages. LoWPANs can be benefit from IP and thus IPv6 networking formed. The combination of IP over LoWPAN is 6lowpan (IPv6 over low power wireless personal area networks). IP in WSNs can eliminate the need of translation gateway and other similar devices used in current WSNs. It allows...
The problem of detecting an anomaly (or abnormal event) is such that the distribution of observations is different before and after an unknown onset time, and the objective is to detect the change by statistically matching the observed pattern with that predicted by a model. In the context of asymmetric threats, the detection of an abnormal situation refers to the discovery of suspicious activities...
With technology scaling, elevated temperatures caused by increased power density create a critical bottleneck modulating the circuit operation. With the advent of FinFET technologies, cooling of a circuit is becoming a bigger challenge because of the thick buried oxide inhibiting the heat flow to the heat sink and confined ultra-thin channel increasing the thermal resistivity. In this work, we propose...
During the last two decades, self-heating has become a significant bottleneck to the continued scaling of microelectronics. This is a particular problem in emerging finFET designs because of the use of thick buried oxide layers which impede heat flow to the heat sink. A possible solution is to use architectural and circuit-level techniques to make the temperature field as uniform as possible on the...
