One of the most important goals for this study is to reveal an effective way to develop systematically the state equations that define the analog circuits (linear, non-linear, timeinvariant etc.) with excess elements. These equations can be depicted in various forms, like symbolic form, numeric-symbolic form, numeric-normal form. At the beginning, we designed the calculation method and afterwards...
An improving efficient algorithm for generation of the state equations in full symbolic, partly symbolic or numeric normal-form is presented. This algorithm has been implemented in a program — called SYSEG — SYmbolic State Equation Generation. The program allows the formulation of symbolic state equations without any inverse of a symbolic matrix, and, by cancellation and simplification of the expressions...
Beam steering using the synchronization has been highly studied in systems of oscillators. Thus the techniques used to analyze and understand the behavior of coupled microwave oscillators advanced. A new approach to analyze such systems based on the state-space representation is introduced in the paper. A very efficient method implemented on computer to automatically formulate the state equations...
New tearing techniques for the systematic formulation of the state equations in symbolic normal-form for linear and nonlinear time-invariant large-scale analog circuits are developed. Some examples are given to illustrate the decomposition procedure and the assignment of the connection sources. The partial symbolic state equations of the opamp μA 741 are obtained using the tearing approach, while...
