An X-Band 6-Bit Hybrid True Time Delay With Linearly-Controlled Gₘ-C All-Pass Filter in 28nm FDSOI CMOS

IEEE Access
This paper presents a 6-bit hybrid True Time Delay (TTD) circuit designed for X-band phased array antenna systems. The circuit integrates a conventional transmission-line (T-line) based TTD structure for short delays (1.56 ps, 3.125 ps, 6.25 ps, 12.5 ps)

A Practical Approach for Fault Location in Transmission Lines with Series Compensation Using Artificial Neural Networks: Results with Field Data

Energies
This paper presents a new method for fault location in transmission lines with series compensation, using data from voltage and current measurements at both terminals, applied to artificial neural networks. To determine the fault location, we present the

A novel single-end fault location method for double-circuit transmission lines

International Journal of Electrical Power & Energy Systems
A new fault location method based on single-end measurements is proposed in this paper. The proposed method decomposes the fault location problem into two sub-problems and uses the voltage and current phasors of one of the line ends to solve the sub ...
