In this paper circuit implementations of cellular processor arrays intended for image processing applications are discussed. It is demonstrated that a departure form the standard CNN model can lead to a significant improvement when processing binary (black/white) images. An asynchronous cellular logic array circuit is presented, which is capable of simulating trigger-waves in an excitable mediu...

In this paper, an analog implementation of the Wavelet Transform is presented. The circuit is based on the Dynamic Translinear circuit technique. From simulations, it is demonstrated that we can scale and shift in time by simply controlling the capacitance or the control current values. The advantage of this topology is the lowpower consumption. The circuit operates from 1-V supply voltage and ...

This paper presents a Web-based graphical tool that makes it possible to view and simulate a working circuit at the layout level. This tool allows one to observe changes in logical levels with a dynamic alteration of the color properties of the graphical elements that characterize the circuit at layout level. The layout view changes colors in function of logic level changes. Two aspects of the ...

A current-mode squarer/divider circuit with a novel translinear cell is presented for automotive applications. The proposed circuit technique increases the accuracy of the squarer/divider function with better input dynamic range and temperature insensitivity. Simulation results show that the variation of the output current is within ±0.2% over the temperature range from −40◦C to 140◦C. key word...

Multiple-threshold CMOS circuit, which has both high and low threshold transistors in a single chip, can be used to deal with the leakage problem in low voltage low power (LVLP) and high performance applications. The high threshold transistors can suppress the subthreshold leakage current, while the low threshold transistors are used to achieve the high performance. In this paper, we will intro...

We address the problem of communicating contrasts in images degraded with respect to their original due to processing with computer graphics algorithms. Such degradation can happen during the tone mapping of high dynamic range images, or while rendering scenes with low contrast shaders or with poor lighting. Inspired by a family of known perceptual illusions: Craik-O’Brien-Cornsweet, we enhance...

The performance benefits of using source-gated transistors (SGTs) in analog large-area electronic circuits are examined practically and via numerical simulations. In current mirror circuits made using thin-film technology, significant advantages are observed for SGT implementations. A comparison of current mirrors implemented with standard field effect transistors (FETs) and SGTs shows that the...

We discuss possible algorithms for interpolating data given in a set of curves and/or points in the plane. We propose a set of basic assumptions to be satisfied by the interpolation algorithms which lead to a set of models in terms of possibly degenerate elliptic partial differential equations. The absolute minimal Lipschitz extension model (AMLE) is singled out and studied in more detail. We s...
