Spice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits
An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...
متن کاملTransient Analysis of Nonlinear Circuits Based on Waves
Circuit-level simulation of complex systems is a challenging task in terms of memory and CPU time. It is thus of great interest to find more efficient methods for circuit-level simulation. At the core of nonlinear circuit analysis is the solution of a system of nonlinear algebraic equations. Solving this system of equations using Newton method requires the decomposition of a large (normally spa...
متن کاملStudy on Shunt State of Track Circuit Based on Transient Current
Track circuit is considered to be one of the means of train detection, its shunt state often misjudged due to the shunt malfunction. Aim at the influence of shunt malfunction on the shunt state of track circuit, a detection method for the shunt state of track circuit according to the transient current was proposed. And the time response of track circuit was obtained by the precise time-integrat...
متن کاملTransient and Steady-State Analysis of Nonlinear RF and Microwave Circuits
This paper offers a review of simulation methods currently available for the transient and steady-state analysis of nonlinear RF and microwave circuits. The most general method continues to be the time-marching approach used in Spice, but more recent methods based on multiple time dimensions are particularly effective for RF and microwave circuits. We derive nodal formulations for the most wide...
متن کاملTransient Crack Propagation in Asymmetric Cruciform Paths
The problem of two cracks emanating from the same origin and propagating asymmetrically at different velocities in an elastic and isotropic solid is treated in this paper. An unbounded and otherwise undisturbed medium and a constant anti-plane loading at infinity were assumed. Techniques of self-similar elastodynamics were utilized in conjunction with analytic-function theory. Since a closed-fo...
