An Envelope Detector Based on Memristive Systems

The Bipolar Memristive Systems with Threshold (BMST) are promising building blocks for analog signal processing. The present work describes their use in designing an envelope detector that can, in particular, be applied in automatic amplitude stabilizers or in the field of computing units, classifiers, as well as in a number of various types of lowvoltage and low-power nonlinear systems for signal processing. The operation of the proposed circuit has been verified via PSpice simulations

Memristor Multiport Readout: A Closed-Form Solution for Sneak Paths

In this paper, we introduce for the first time, a closed-form solution for the memristor-based memory sneak paths without using any gating elements. The introduced technique fully eliminates the effect of sneak paths by reading the stored data using multiple access points and evaluating a simple addition/subtraction on the different readings. The new method requires fewer reading steps compared to previously reported techniques, and has a very small impact on the memory density. To verify the underlying theory, the proposed system is simulated using Synopsys HSPICE showing the ability to achieve a 100% sneak-path error-free memory. In addition, the effect of quantization bits on the system performance is studied. © 2014 IEEE

Memristors : a journey from material engineering to beyond Von-Neumann computing

Memristors are a promising building block to the next generation of computing systems. Since 2008, when the physical implementation of a memristor was first postulated, the scientific community has shown a growing interest in this emerging technology. Thus, many other memristive devices have been studied, exploring a large variety of materials and properties. Furthermore, in order to support the design of prac-tical applications, models in different abstract levels have been developed. In fact, a substantial effort has been devoted to the development of memristive based applications, which includes high-density nonvolatile memories, digital and analog circuits, as well as bio-inspired computing. In this context, this paper presents a survey, in hopes of summarizing the highlights of the literature in the last decade
