The objective of the project is to develop a model for the capacitive ultrasonic transducer described in the Ladabaum et al., [1] paper. The main element of the transducer is a metalized silicon nitride membrane suspended on a rigid support above a heavily doped silicon bulk. The cavity under the membrane is vacuumed. When a voltage is applied between the metalized membrane and the bulk, the Coulomb...
In this paper a parallel implementation of the RLC-circuit dimensions reduction algorithm based on the Y-Δ transformation is considered. The algorithm in question is based on the modified Sangiovanni-Vincentelli cluster algorithm. Simulation results are given, which prove efficiency of the proposed solution.
In this paper a model for the capacitive ultrasonic transducer is described. The main element of the transducer is a metalized silicon nitride membrane suspended on a rigid support above a heavily doped silicon bulk. The model developed in the project is based on the lumped parameter representation of the membrane, is easy to characterize, and is suitable for small and large signal analyses.
In this paper the modifications of the RLC-circuit dimension reduction algorithm are considered, which provides less total number of newly created elements during the reduction process and, respectively, less time consumption and memory requirements for the circuit storage.
In the paper the problems of choosing an objective function type when adjusting mechanical components' macromodel parameters are considered. The most used objective function types which cover the majority of practical optimization tasks are specified, and their analysis is conducted. The recommendations on choosing an objective function type depending on the task's features are proposed.
In this paper the possibilities to present a system of ordinary differential equations describing any non-electrical object as an equivalent electrical circuit depending on the form of an ODE system are considered.
