Simulation of reflected voltages using V-Q characteristic of a load for crosstalk simulation

In this paper, a new simulation method for crosstalk simulation is described. To simulate the crosstalk accurately, accurate simulation of reflected voltages from loads is required. The authors have studied the simulation method of reflected voltages using a dynamic C-V characteristic. However, this method has a problem that the procedure of calculation becomes complicated. This paper proposes a new simulation method using V-Q characteristic. The proposed method reduces the amount of calculation for the simulation. The simulation accuracy is little lowered though the amount of calculation is much reduced.

I. Introduction

As is seen in recent advancement in electrical devices, miniaturizing circuit board and speeding up of transmitted signal advance remarkably. Accompanied to miniaturizing circuit board and speeding up of transmitted signals, space between transmission lines becomes narrow, and transition time of transmitted signals becomes short. However, narrowing spaces between transmission lines and shortening transition time increase crosstalk. This causes malfanction of electric devices. In design of small electrical circuits, a technique to predict crosstalk precisely is necessary to prevent errors.
