This paper presents a new way of modeling the integrators non-idealities for high-level sigma-delta modulator models. In this way, designers can correlate directly the integrator specifications like finite DC gain, Gain-Bandwidth product and Slew Rate with modulator performances (SNR, SNDR). Taking into account capacitive effects, a high degree of accuracy is obtained which is verified by transistor...
Ferroresonance is one of the most destructive transient phenomena in power systems. This complex phenomenon involves the association of nonlinear magnetizing inductances and capacitances, and may be initiated in many different ways, which makes its characterization very difficult. This work links EMTP and MATLAB and presents some computer tools that have been developed for assessing ferroresonance...
Nowadays the term ferroresonance is firmly established in the power system engineer's vocabulary as one of the most destructive transient phenomena, which may cause failures in power equipment such transformers, cables, or arresters. Its complex non-linear behavior makes difficult its characterization. This work links EMTP and MATLAB to presents some techniques for the assessment of ferroresonance...
This paper presents the full design, operational principle, structure and frequency response simulation of one-port Surface Acoustic Wave (SAW) Resonator using Micro Wave Office (MWO) and MATLAB used for passive wireless sensing of various measurands. Since SAW Resonators are widely used in radio frequency sensing application, the development and evolution of present day SAW devices has been possible...
