Ultra High-Speed Hardware Emulator for Real-Time Fault Location in Multi-Conductor Power Systems

Maher Kayal, François Krummenacher, François Pierre Gaugaz

This research presents a transmission line model aimed for the fault location in power systems using a method based on the Electromagnetic Time-Reversal (EMTR). The discrete-time model simulates the waves travelling in the line by means of many unit delays ...

A 32kHz crystal oscillator leveraging voltage scaling in an ultra-low power 40nA real-time clock

Maher Kayal, Luca Rossi, François Krummenacher, Mathieu Yves Hervé Coustans

In this paper, an ultra-low power consumption crystal oscillator embedded in an RTC module (ASIC and its crystal resonator) is presented. The technique leverages oscillation amplitude and loads capacitance scaling; it incorporates transistor level merging ...

Implementation Guidelines for a Real-Time Fault Location System in Electrical Power Networks

Maher Kayal, François Krummenacher, François Pierre Gaugaz

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 numb ...
