Pulsed-field wireless interconnects in digital integrated circuits — A time-domain signal transfer and electromagnetic emission analysis

The loop-to-loop pulsed electromagnetic field wireless signal transfer is investigated with a view on its application in microelectronic systems and devices. The transmitting loop is excited with a monocycle pulse electric current. Closed-form expressions are derived for the emitted magnetic field and for the open-circuit voltage of the receiving loop in dependence on the mutual orientation of the loops and the parameters of the feeding pulse. Numerical results are given for some configurations that are representative for microelectronic wireless signal transfer. They are indicative for the potentialities of the pulsed-field wireless signal transfer concerning the received signal characteristics and the compliance with regulatory specifications on Electro Magnetic Emission.
