SPICE simulation
Laboratory measurements and simulations of Multiconductor Transmission Lines ended in electronic components. There are datasets corresponding to the following cases:
- one-wire transmission line ended in a diode
- one-wire transmission line ended in an op-amp
- two-wire transmission line where one of the wires is ended in an op-amp (cross-talk study), the other excited by either sin or a square pulse

This document presents a simple method for using time-domain simulations to extract an AC small-signal model of the power stage in a power converter. Such extraction is important for simulating feedback loop gain and assessing the stability of complex power converter topologies, such as resonant converters or converters with advanced switch control. With the proposed approach, a single time-domain simulation run is sufficient to extract the small-signal model, making the process time-efficient.
