Physical Unclonable Functions (PUFs) are cryptographic primitives that can be used to generate volatile secret keys for cryptographic operations and enable low-cost authentication of integrated circuits. Existing PUF designs mainly exploit variation effects on silicon and hence are not readily applicable for the authentication of printed circuit boards (PCBs). To tackle the above problem, in this...
With the purpose of reducing the cobalt content in diamond tools, Cu-Fe based matrixes were prepared by vacuum and pressure-assisted sintering under a pressure of 13 MPa at 740 °C, 780 °C and 820 °C. The effects of sintering temperature on microstructures and mechanical properties of the sintered matrix were investigated by X-ray diffraction analysis, electron probe micro-analyzer, and universal mechanical...
By surmounting various obstacles across the spectrum from material synthesis to device fabrication and circuit considerations, we provide a solid foundation so that carbon-based technology can move forward towards the vision of engineering VLSI circuits, but further research is still needed to realize the material potential such as higher density CNT synthesis, better metal to CNT/graphene contacts,...
Ultra-wideband (UWB) receivers can resolve individual multipath components (MPCs), due to the signal occupied a large bandwidths, so they are capable of accurately estimating the time of flight of the signal. To realize high-accuracy indoor localization, a novel UWB locating scheme through estimating the round trip time (RTT) of UWB signal is proposed. Each reference station (RS) transmits the baseband...
With the increase of small magnetic devices, and high-frequency magnetic technology improving, integrated magnetic technology as a magnetic device can improve the power density, volume decreased magnetic pieces of the application of modern technology is in the power electronics plays an increasingly important position, increasingly extensive research. This paper introduces the magnetic circuit model...
