Local and Direct EM Injection of Power Into CMOS Integrated Circuits

Abstract

The paper aims at demonstrating experimentally that the tiny Electro Magnetic (EM) coupling between the tip end of a micro-antenna is sufficient to locally and directly inject power into CMOS Integrated Circuits (IC). More precisely, experimental results show that such electrical couplings are sufficient to disturb, with and without removing the IC package, the behavior of 90nm CMOS Ring Oscillators, a representative structure of CMOS logic but also a constituting element of some True Random Number Generators (TRNGs) or clock generator.
