Abstract

As the core device of electronic equipment, integrated circuit (IC) usually produces large high-frequency electromagnetic interference. In order to study the generation mechanism and suppression methods of such noise, accurate noise measurement and extraction must be carried out. At present, the measurement standard of chip level electromagnetic compatibility is not perfect, and the high-frequency characteristics of pin noise are difficult to be measured accurately. In order to achieve accurate chip pin RF voltage measurement, this paper designs a chip pin RF voltage measurement method, establishes the 3D model of the chip pin RF voltage measurement module, studies the effects of its wiring, via, substrate dielectric constant and other parameters on its high-frequency signal transmission performance, and then optimizes the module. Simulation and experimental results show that the optimization method effectively improves its high-frequency signal transmission characteristics. Finally, the RF voltage of the output pin of the active crystal oscillator is extracted by using the detection system designed in this paper.
