Equivalent circuit model for active-layer photomixing: Parasitic-free modulation of semiconductor lasers [PDF]

open access: yes, 1988
Direct modulation of a laser diode by active-layer photomixing is studied in terms of an equivalent circuit model. The model shows that this modulation technique achieves nearly perfect immunity to package, chip, and junction-related parasitic effects so

A circuit modeling technique for the ISO 7637-3 capacitive coupling clamp test [PDF]

open access: yes, 2018
In this paper, we propose a transmission-line modeling technique for the ISO 7637-3 capacitive coupling clamp (CCC) test. Besides modeling the test bench, special attention is devoted to the CCC itself, for which an equivalent circuit is constructed ...

Modeling, Prediction, and Results Correction of PDSH Circuits for Nanosecond Pulse Peak Detection

open access: yesApplied Sciences, 2023
The peak detect and sample hold (PDSH) circuit is an important component of the light detection and ranging (LiDAR) system, because the PDSH circuit can correct the walk error of the time discriminator, and distinguish different objects at the same ...

Implementation of an Alternative Frequency-Dependent Three-Phase Transmission Line Model Based on the Folded Line Equivalent Model in MatLab-Simulink

open access: yesEnergies, 2022
This paper proposes an alternative multiconductor transmission line model that combines the folded line equivalent with the modal transformation. The folded line equivalent decomposes the nodal admittance matrix of a transmission line into its open ...
