In brief

Abstract

PAGE 847 Researchers in Taiwan have proposed a Class-C differential voltage-controlled oscillator (VCO) with dynamic back-gate bias. The VCO is designed and implemented in 0.18µm BiCMOS process, and they have demonstrated that the VCO dramatically minimizes start-up time and power consumption. PAGE 826 A high-gain antenna has been developed by researchers in Korea. The design achieves high efficiency and low sidelobe level, whilst easily managing dual-orthogonal polarisation through distributing the phase difference to only two ports. The work can be applied to smart wireless backhaul systems and massive MIMO antennas. VCOs are vital components in wired and wireless communication systems PAGE 856 By incorporating an empirical noise model in the image generation process, researchers in Denmark have developed a method for generating synthetic Kinect v1 depth images with a high degree of realism. This technique can be used in, for example, the training of algorithms, analysis of uncertainties, evaluation of algorithms, analysis of visual features, and offline programming or prototyping. The cross-dipole antenna shows strong performance in terms of impedance, bandwidth, gain and isolation PAGE 885 Researchers from China have calculated the coverage probability of wireless data transmission between multiple unmanned aerial vehicles (UAVs). Using frequency bandwidth dependent models for air and ground communication channels, the method defines guidelines for optimising the design of aerial networks between multiple UAVs. Results show the optimum distribution and altitude of UAV networks to maximise communication capacity in disaster response. The Kinect can be used in a surprising number of applications, from training of algorithms to online programming PAGE 881 Research from China proposes a new approach to expand GaAs Schottky diode modelling. The complexities associated with existing 3D Schottky diode models are reduced by setting the same permittivity values for approximate materials. Experimental measurements demonstrate the accuracy of the proposed model. The method provides a simple but accurate approach for predicting device performance of a Schottky diode.
