In recent years, ultra-wideband (UWB) has emerged as a preferred choice for precise wireless indoor localization and navigation systems. The inherently better ranging performance and stronger resistance to multipath fading compared to previously used technologies have led to increased research on the performance of UWB devices. However, regulatory requirements on transmission power constrain UWB communication range. This paper studies the impact of different PHY settings of an 802.15.4z-compliant SiP, the Qorvo DWM3000, in a comprehensive set of real-world measurements. Furthermore, we focus on range maximization and high reliability when power consumption or air utilization is not constricted. Results show that with a commercial off-the-shelf UWB SiP, a maximal reliable range of 125 meters with an overall mean accuracy of 25.1 cm can be achieved while staying within the regulatory limits. © 2024 IEEE.

We present the development and implementation of an algorithm for tracking the position of a mobile network node. The tracking algorithm uses distance measurements between a mobile node and multiple anchor nodes. The first stage of our algorithm calculates the initial position from distance measurements relative to three (2D) or four (3D) anchors of known position. In a second stage this initial position is improved and tracked over time by feeding a Kalman filter with new distance measurements to neighboring anchor nodes of known position. Both the algorithm and the related communication protocol have been implemented and verified in multiple scenarios by using the event driven OMNET++ network simulator. © Springer Science+Business Media B.V. 2008.

A significant trend towards developing soft core based designs has been observed for the last few years. The emphasis is on reduction of time to market and bridging the growing gap between technology capacity and design productivity. The paper briefly presents the design of a configurable microcomputer family model based on a VHDL soft core. Modeling process with emphasis on coding style is mentioned. The paper also proposes a virtual component configuration tool that gives the core user an effective way to set up the model of the microcomputer family upon the need of particular end users, and introduces the implementation of industrial microcomputer series based on the model. The work on the extension of the soft core with regard to its reusability, as well as on the development of a configurable model of microcontroller class based on the soft core is being done. © 2001 IEEE.

Large-Range and High-Sensitivity Displacement Sensing Based on Extrinsic Fabry-Perot Interferometer Assisted Microwave Photonic Filter

Displacement is a pivotal physical parameter, and advancements in displacement sensor technology have enabled the creation of a diverse array of physical and mechanical sensors through seamless integration with mechanical transducers. In this study, we introduce a displacement sensing technique leveraging an extrinsic Fabry-Perot interferometer (EFPI) assisted microwave photonic filter. By translating displacement-induced variations in the EFPI’s optical reflection into peak frequency shifts within its frequency response, we achieve large-dynamic-range displacement measurements with outstanding signal quality and demodulation ease. Proof-of-concept demonstrations showcase a substantial 5 mm range with a remarkable sensitivity of 1.148 GHz/mm, achieved using a basic single-mode fiber-based EFPI with a movable external mirror. Besides, nm-scale displacement monitoring is experimentally validated through a phase-measurement approach. Notably, the sensitivity and dynamic range can be tailored by adjusting the microwave photonic filter system’s parameter, i.e., the dispersion parameter of the dispersive element in the system. Furthermore, we introduce a strategy to enhance the dynamic range further by employing a virtual frequency down-conversion technique with an additional interferometer. This proposed technique opens avenues for developing a series of high-sensitivity and broad operating-range physical and mechanical sensors based on a simplified EFPI measurement configuration. © 1963-2012 IEEE.

This paper presents a low power, low phase noise, and small chip area transformer-based PMOS-only stacked-g», LC VCO in a 28-nm process. Both the top and bottom use PMOS cross-coupled pairs to provide negative resistances with suppressing the flicker noise. An interleaved transformer is used to get a higher coupling coefficient to achieve small chip area and high passive voltage gain. The VCO exhibits a wide turning range from 4.2 to 5.6 GHz, and low phase noise from -120 dBc/Hz to -113 dBc/Hz at 1MHz frequency offset, respectively. It consumes minimum 678 μ W and maximum 680 μ W from a 0.8V supply voltage which does not require internal LDO or DC-DC converter to reduce the supply voltage. © 2022 IEEE.

Dynamic reconfiguration is a promising approach for resource efficient utilization of microelectronic systems. However, work on general approaches to model reconfigurable hardware is quite rare. Therefore, we have developed a new analytical model, which can be used for the analysis of the various approaches to dynamic reconfiguration. Based on our model we define metrics for partial reconfiguration to evaluate different system approaches. Our main objective is to analyze placement algorithms for partially reconfigurable architectures. The model is able to consider miscellaneous constraints and cost parameters for online placement. Thus, placement can be adapted to dynamically changing system environments.

A 128-kHz RC time-constant-based relaxation oscillator is designed in 180-nm CMOS for ultra-low-power applications. The chopping structure and replica path delay loop are employed in this work to eliminate the effect of comparator offset and path delay respectively, leading to a frequency accuracy of ±0.21% over the temperature range from-20°C to 100 °C. The power consumption is 344 nW with 0.8-V supply, resulting in an energy of 1.55 nW/kHz. © 2021 IEEE.

This extended abstract presents first results of a research project that addresses an approach to verify the functionality of Programmable Logic Controllers (PLCs). The main feature of this technique is concentrated on its ability to automatically generate functional test cases for a test platform completely from a formal test specification without any implementation details. The resulting platform provides the environment of the PLC, consisting of the PLC testbench in Structured Text (ST) format and test patterns. The specification is modeled in a complete property set using InTerval Language (ITL), while input and output signal types are defined using VHDL. The presented algorithm uses inherent properties of the formal test specification (completeness, consistency) to automatically generate a minimal set of test cases, covering all functional states as well as corner cases. © 2020 MBMV 2020: Methoden und Beschreibungssprachen zur Modellierung und Verifikation von Schaltungen und systemen - GMM/ITG/GI-Workshop.

High level synthesis using operation properties

High level synthesis using operation properties

We propose a high level synthesis approach to generate RT level hardware from a specification of operation properties. The property language is called InTerval Language (ITL) and we assume the set of properties is complete, such that the properties alone are strong enough to map every possible sequence of input data to exactly one sequence of output data. A major advantage of using operation properties as a design method is the existence of commercial tools to check the completeness and consistency of the property set. Furthermore, operation properties are well suited for specifications of consecutive operations of finite length. We show the practicality of our method by implementing a particle filter for a localization application. © 2010 Springer Science+Business Media B.V.
