碩士 === 國立中央大學 === 電機工程學系 === 85 === This thesis presents an equivalent circuit approach for one-and two-dimensional numerical mixed-level device and circuit simulation. In such an equivalent circuit approach, Poisson's andContinuity equations are formulated into a subcircuit format suitablefor general circuit simulators. Different from conventional approaches,our approach is conceptually simple and the extension of this model tothree-dimensional semiconductor simulation is just straightforward. It'salso easy to implement this model in many existing circuit enivornmentssuch as HSPICE. The utility of this new model in mixed-level simulationis demonstrated by applying to our own circuit simulator and HSPICE.Various applications such as PN diode switching circuit, SOS test circuit,MESFET, and MOSFET are taken as examples to verify the proposed algorithm.By the use of this technique, it's helpful for us to investigate the interactions between semiconductor devices and the circuits in whichthey are embedded from physical point of view.
