Application of LE-FDTD method to HF circuit analysis LE-FDTD法在高频电路分析中的应用

{"title":"Application of LE-FDTD method to HF circuit analysis","authors":"P. Ciampolini, L. Roselli, S. Catena","doi":"10.1109/SISPAD.1996.865270","DOIUrl":"https://doi.org/10.1109/SISPAD.1996.865270","url":null,"abstract":"A circuit simulation technique is discussed, which accounts for the \"full-wave\" analysis of signal propagation along the interconnections of an arbitrary circuit, including active, non-linear devices. A number of electromagnetic propagation effects have significant influence over high-frequency (either analog or digital) circuit performances and can be accurately modeled by means of the approach described: among them, interconnection behavior, cross-talk phenomena, package interactions. Conventional circuit CAD tools allow the analysis of such effects by resorting to equivalent-circuit, lumped-element descriptions of interconnecting lines. Although this technique is highly computationally efficient, the definition of the equivalent circuit topology and the estimation of its parameters often relies on rather drastic approximations, because of the inherently \"distributed\" nature of most propagation effects. To tackle this problem, the Lumped-Element, Finite-Difference Time-Domain (LE-FDTD) technique has been conceived. Within this approach, SPICE-like compact device models are coupled to the numerical solutions of Maxwell's equation over distributed domains. The extension of LE-FDTD technique to circuits including GaAs MESFET devices is reported, and a few simulation examples are illustrated.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.

An analytical function /spl tau/(E) is desirable that takes into account the image force in a better way than by the lowering of a trapezoidal barrier. Based on the observation that the tunnel probability is mainly determined by the action of the barrier, we propose a \"pseudobarrier\" method.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.

Since nonequilibrium carrier transport becomes important in the HBTs, carrier energy must be considered in the modeling of them. For this purpose, an energy transport model that uses hydrodynamic equations derived from the Boltzmann equation is attractive and has been applied to AlGaAs/GaAs HBTs. In the HBTs, material parameters should depend on material composition as well as carrier energy and the doping densities. However, up to now, methods of giving parameters in the transport equations were too crude. A constant value of energy relaxation time was assumed and parameters for GaAs at a certain doping density were also assumed for all x in Al/sub x/Ga/sub 1-x/As. In this work, a method of giving composition-, doping-, and energy-dependent transport parameters is proposed, and successfully applied to the simulation of AlGaAs/GaAs HBTs.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.
