This research presents a discrete-time transmission line model based on the propagation of travelling waves. In this approach, the transmission line is emulated by means of many interconnected elementary delay cells implemented with switched-capacitor (SC) circuits. The accuracy and limitations of this method is compared to existing transconductance-capacitor (gm-C) solutions and is evaluated in the...
This paper presents constraints involved in the microelectronic implementation of a transmission line model based on transconductor-capacitor (gm-C) topologies. The presented line model, based on the discretization of a transmission line into a finite number of series inductors and shunt capacitors, is aimed for the fault location in power network, a technique using the Electromagnetic Time-Reversal...
This paper explores the potential and limitations of analog integrated circuit techniques for the simulation of low-loss or lossless 1D or 2D transmission mediums. In this approach, a transmission line is mapped into a ladder consisting of N identical LC elements, each modeling a finite length increment of the line. Inductors are then emulated by a gyrator-capacitor combination, yielding a classical...
