ABSTRACT This letter proposes a precision‐improved sampling switch that requires only two additional transistors and one inverter, with all devices implemented using N ‐type transistors. The design introduces a source‐drain shorted dummy transistor to compensate for or cancel out the charge injection from the main switch and incorporates an additional discharge switch to suppress charge leakage a…

ABSTRACT Large language models can translate natural language into robot code but often produce physically infeasible behaviours, particularly in tool‐use tasks requiring precise contact reasoning. We propose a closed‐loop framework that integrates code generation, physical simulation, and iterative correction to ensure physically valid tool‐use primitives. Failures such as collisions and misalig…

ABSTRACT We propose an Au‐free ohmic contact for diamond using a Ti/Al/Ti/TiN multi‐layer metal stack, achieving an ultra‐low specific ohmic contact resistance of 3.9×10 −5 Ω·cm 2 . Building on this optimized contact structure, diamond Schottky barrier diodes (SBDs) are fabricated, exhibiting a breakdown voltage of 1770 V. This work provides a feasible and cost‐effective route for the large‐scale…

ABSTRACT Multivariate time series forecasting is crucial in intelligent systems and widely applied to tasks like traffic flow prediction. Existing spatio‐temporal forecasting models struggle to capture interactions between temporal dynamics and spatial dependencies, limiting their representation of complex spatio‐temporal patterns. To address this, we propose a multivariate time series forecastin…

ABSTRACT This letter presents a high‐ Q tunable waveguide (WG) filter with constant absolute bandwidth (CABW). By adjusting the penetration depth of a single dielectric tuning element into the filter, frequency tuning is readily obtained without a complicated mechanism. Modified cavity perturbation theory (CPT) is adopted for the first time to deduce the quantitative relationship between the pene…

ABSTRACT The 4D mmWave radar point clouds are extremely sparse and noisy, which limits their geometric expressiveness for radar‐based 3D object detection. To solve the problem, a dual‐view radar reconstruction framework is proposed to simultaneously generate a bird's‐eye‐view occupancy map and a perspective depth map from raw radar measurements. The two complementary views are back‐projected and …

ABSTRACT Contactless smart cards operate using power harvested through inductive coupling, which requires the use of extremely low‐power, supply‐tolerant digital architectures. This work presents a self‐timed RISC‐V RV32I microprocessor that replaces the global clock with an asynchronous finite state machine based on a handshake protocol. This control scheme naturally adapts to supply voltage flu…

ABSTRACT The detection and parameter estimation of radar manoeuvring targets has attracted more and more attention in recent years. Due to the high manoeuvrability of the target during radar observation, range migration and Doppler migration will occur and severely deteriorate the coherent integration performance of the target echo. In this letter, an efficient manoueuvering target detection meth…

ABSTRACT Convolutional neural networks are challenging to deploy on resource‐constrained computing platforms due to their high storage and computational demands. Mixed‐precision quantization can mitigate these issues by assigning different bit‐widths per layer. However, finding an optimal quantization policy is challenging due to the exponential size of the policy search space and the need for ex…

ABSTRACT The adiabatic capacitive artificial neuron (ACAN) has been previously shown to offer the potential for ultra‐low power computation in full custom analogue ASIC designs. However, it did not consider how a real‐world, software‐trained, artificial neuron (AN) could be mapped robustly onto the circuit. In this paper, we describe how an AN, with positive‐valued weights, bias and a binary acti…

ABSTRACT The dielectric characterisation method using an open circular waveguide radiating into a material is a well‐known method that offers many advantages but also has certain disadvantages that limit its use. The main disadvantages are the presence of multiple solutions during extraction and a calibration method that could be improved. Our studies have led to solutions that allow convergence …

ABSTRACT A new miniaturised co‐aperture in‐band full‐duplex antenna with good T x /R x isolation for wearable applications is proposed in this letter. The octagonal patch, which worked as the radiating structure, is minimised by using multiple loading structures, including etching narrow slots distributed circumferentially, loading stubs and rectangular parasites. A pair of cross‐shaped slots and…

ABSTRACT The sensing‐based semi‐persistent scheduling (SB‐SPS) mechanism in 5G new radio vehicle‐to‐everything Mode 2 suffers from wireless blind spots caused by hidden terminals and half‐duplex constraints, which can lead to persistent collisions in dense traffic. This letter proposes a resource map sharing service, where a roadside unit aggregates a wider‐area resource‐occupancy map and shares …

ABSTRACT This work investigates improving dielectric resonator antenna (DRA) radiation bandwidth through the integration of linearly graded permittivity profiles. Using Characteristic mode analysis (CMA), it is shown that such profiles broaden modal distribution, consequently extending the bandwidth of the dominant resonant mode. The proposed antenna design is enabled by additive manufacturing te…

ABSTRACT Spiking neural networks (SNNs)‐based radar gesture recognition has gained significant attention for its ability to enhance computational efficiency. To better exploit their potential, SNNs are often integrated with effective compression techniques to enable practical deployment in resource‐constrained edge environments. However, conventional pruning approaches either necessitate computat…

ABSTRACT This letter presents an adaptive temperature compensation technique for a subthreshold analogue front‐end (AFE) in low‐power application. The conventional subthreshold AFE suffers from significant temperature dependency, compromising performance over a wide operating range. To overcome this critical issue, the proposed technique provides adaptive performance compensation, driven by a com…

ABSTRACT Traditional laboratory management relies heavily on manual oversight and static threshold‐based fault diagnostics, which are inadequate for addressing the dynamic, individualised needs of contemporary environments. To address these challenges, we proposed an intelligent laboratory management framework, designed to enable secure and autonomous equipment monitoring. The system employed a h…

ABSTRACT In the natural environment, the unstable radar measurement noise can degrade the tracking performance of the manoeuvering target. In this Letter, the iterative formulation of the noise is simplified, and the noise‐adaptive matrix is introduced to calculate the fading factor of the strong tracking algorithm so that the effect of measurement noise on the fading factor can be corrected in r…

ABSTRACT To demonstrate compliance of flight simulation device (FSD) data packages with regulatory requirements, certification subjects must meet multiple error tolerance objectives. This paper presents a rapid parameter tuning method based on multi‐objective optimisation utilising neural network surrogate models, which improves the efficiency of multi‐system joint simulation. In comparison to th…
