The analysis and optimization of the npvnp avalanche diode structure that includes two avalanche regions have been realized on basis of the nonlinear model and special optimization procedure. The admittance characteristics of the DAR diode were analyzed in very wide frequency band from 30 up to 360 GHz and had been optimized for the third frequency band near the 300 GHz.

This paper proposes new admittance matrix models to approach the behavior of fully-differential Operational Transresistance Amplifiers (OTRAs) and Current Operational Amplifiers (COAs). The infinity-variables method is used in order to derive the new generalized models. As a consequence, standard nodal analysis being improved to compute fully-symbolic small-signal characteristics of fullydiffer...

A model-based approach to control system design is developed for regulating the discharge flows at outlets of a pipeline network supplied by an irrigation channel. The open channel also controlled automatically regulate supply-point water level. hydraulic pressure source therefore dynamic when flow load varies. Regulation piped achieved adjusting outlet valves on basis specified demand and sens...

Transformer model; Load flow analysis; Symmetrical components; Distribution systems Abstract This paper presents an efficient approach for developing three-phase transformer admittance matrices in the radial power-flow analysis. The proposed transformer model overcomes the singularity problem of the nodal admittance submatrices of ungrounded transformer configurations. This has been achieved by...

Multi-terminal high voltage direct current (HVDC) systems, together with AC transmission systems and source converters (VSCs), form hybrid AC/DC grids complex dynamic transient interactions. VSCs characterization taking into account DC- AC-side dynamics in order to study these interactions is not yet well solved. This paper presents a three-port transfer admittance-based matrix model of that ca...

A rectangular waveguide is terminated by an infinite conducting flange and radiates into half-space. Modal expansions of the TE and TM waveguide fields lead to Hermitian forms for the incident an8 reflected waveguide power (Pws = Pwg+ Pwg-) in terms of the corresponding electric field mode amplitude vectors and a diagonal field admittance matrix [Yj. The power radiated from the aperture is expr...
