Computing-in-memory (CIM) is considered a feasible solution to the acceleration of multiply-accumulate (MAC) operations at low power. The key CIM parallel MAC in memory domain, and thus reductions power consumption memory-access latency. Resistive random access (RRAM) can be good candidate for given its data nonvolatility, high density, low-latency read-out, multilevel representation, inherent ...

This paper introduces a Transimpedance Amplifier (TIA) design capable of producing an incremental input resistance in the ohmic range, for signals microampere such as are encountered instrumentation electrochemical ampero-metric sensors, optical-sensing and current-mode circuits. low input-resistance is achieved using stage incorporating negative feedback. In Cadence simulation exemplary 180 nm...

A subwavelength metamaterial perfect absorber (MPA) in optical communication band was proposed and tested using the finite-difference time-domain method. The is periodic comprises a top layer of diamond silicon surrounded by L-shaped gold on substrate. It can achieve dual-band absorption, one peaks band. By changing gap (g) between two adjacent pieces silicon, thickness (h) layer, resonance wav...

Abstract All-dielectric metasurfaces have great potential as highly sensitive refractometric sensors relying on their spectral shifts because of an extensive range design flexibilities and smaller absorption losses than plasmonic platforms. However, simultaneously realizing both high quality ( Q ) factors the large interplay light with external medium in such photonic remains one key challenges...

A metal–insulator–metal (MIM) waveguide consisting of a circular split-ring resonance cavity (CSRRC) and double symmetric rectangular stub (DSRSW) is designed, which can excite quadruple Fano resonances. The finite element method (FEM) used to investigate influences geometric parameters on the transmission characteristics structure. results show that resonances are excited by interference betwe...

The Kerr nonlinear optical performance of silicon nanowire waveguides integrated with 2D layered graphene oxide (GO) films is theoretically studied and optimized based on experimentally measured linear parameters the GO films. strong mode overlap between nanowires highly yields a significantly enhanced nonlinearity for hybrid waveguides. A detailed analysis influence waveguide geometry film thi...

Abstract In order to meet the demand for large-scale magnetic field testing, this paper proposes a D-shaped magneto-refractive photonic crystal fiber (MRPCF) based on surface plasmon resonance (SPR) by using erbium-doped material. By varying diameter, location, and number of layers air holes, four different Models A, B, C, D structures are created, corresponding sensing properties analyzed. The...

With high sensitivity imaging arrays, accurate calibration is essential to achieve the limits of detection of space observatories. One can simultaneously extract information about the scene being observed and the calibration properties of the detector and imaging system from redundant dithered images of a scene. There are large differences in the effectiveness of dithering strategies for allowi...
