In this paper we present a novel noise reduction method using Coordinate Logic (CL) filters applied to printed text and handwriting images. CL Filters and their associated Coordinate Logic Operations (CLOs) are widely used in common practical image process applications like noise removing, magnification, opening, closing, skeletonization, coding, edge detection, feature extraction, and fractal modeling...
An ultra-low power adjustable triangle wave generator with a multi tunable amplitude and frequency is introduced in this paper. The proposed circuit consists of a Schmitt trigger and a current source. The overall nonlinearity of the TWG circuit is less than 2% in its current-to-frequency transfer characteristic. The tunable frequency and amplitude range are 10KHz to 40KHz and 0.1V-1.7V respectively...
The gate tunnelling current of MOSFETs is an important factor in modelling ultra-small devices. In this reported work, the gate tunnelling current in present-generation MOSFETs is studied. Presented is a model for the gate tunnelling current in MOSFETs having ultra-thin gate oxides. In the proposed model, the electron wavefunction at the semiconductor-oxide interface is calculated and inversion charge...
