Abstract :
A method for measuring current and voltage distributions on digital integrated circuits (ICs) at harmonic frequencies is proposed. This method counters interference by electromagnetic fields adjacent to the IC, even at frequencies that exceed 1 GHz, because it allows the use of a small probe with a high self-resonance frequency. Digital IC current and voltage distributions were measured at GPS frequency using this method. It is shown that the measured distributions can be used to estimate effective positions for anti-adjacent-interference shielding in the IC
