A 10-bit 120MS/s successive-approximation-register (SAR) analog-to-digital converter (ADC) in 40-nm CMOS is presented. To diminish the fluctuation of common-mode voltage (VCM) and switching energy during conversion, a VCM-stable scheme adopted without increasing design complexity to VCM buffers. Moreover, tri-switch sampling employed this design. Together with binary-scaled recombination weight...

Tunable and ultrasensitive surface plasmon resonance (SPR) sensors are highly desirable for monitoring stress hormones such as cortisol, a steroid hormone formed in the human body’s adrenal glands. This paper describes detection of cortisol using bimetallic SPR sensor based on anisotropic two-dimensional material, i.e., phosphorene. Thicknesses bi-metal layers, copper (Cu) nickel (Ni), optimize...

Edge indicating operators such as gradient, mean curvature, and Gauss curvature-based image noise removal algorithms are incapable of classifying edges, ramps, flat areas adequately. These often affected by the loss fine textures. In this paper, these problems addressed proposed a new coefficient diffusion for removal. This consists two edge operators, namely fractional-order difference curvatu...

We propose a simple solid–liquid–solid triple layer biosensor platform based on bound states in the continuum (BICs) and Fano resonances to detect acoustic properties of liquids apply method mixture water albumin with various concentrations. The is composed an epoxy as solid albumin–water liquid layer, entire system immersed water. In this work, we show that structure exhibits high sensitivity ...

This paper presents a single-frequency reflective-mode phase-variation microwave sensor devoted to the dielectric characterization of materials. The device is implemented in coplanar waveguide (CPW) technology and consists two parts: (i) sensing region, step-impedance resonator (SIR) as termination CPW transmission line, (ii) design cascade high/low impedance quarter-wavelength inverters, used ...

In this equation, n represents the number of Figures of Merit (FoMs) that are to be combined, xi represents the output of the scoring function for the ith FoM and wi represents the weight of importance assigned to the ith FoM. The Product Tradeoff Function is commonly used for example in computing cost to benefit ratios and in doing risk analyses. Unfortunately, the published equation on page 1...

Surface magneto-plasmon (SMP) sensors have attracted continuous attention due to their field enhanced signal-to-noise ratios, sensitivities, and detection limits. Although many progresses been achieved in the nanodots, nanorods, or nanodiscs, few studies conducted on films containing arrays of nanopores nanoholes. SMP based could be much more promising for future ultrasensitive optical detector...
