Novel non-direct signal detect probing and modeling developed by the Biot-Savart theorem

摘要

In this study, the main keypoint is non-contacting measurement. The traditional contacting probe has numerous disadvantages, including low mobility, high cost, high damaged rate, and so on. A non-contacting probe designed efficacy with broadband, well reproducibility, well directivity and low loss coupling to transmit or receive a signal between different chips or ICs in 3DIC application, and establishing physical model up to 10 GHz with coupling effect and loop effect to restore the signal radiation. In addition deriving from the electromagnetic theorem discovers either the current flow or the scattering parameter. A complete reduction theory to compensate the coupled signal measuring by the non-contacting probe is needed. The result of the restore theory is highly matched to the model with lumped elements, and the result of the derived theory is similar to actual measurement that can detect the signal in ICs.
