Extraction method for impedance of ARM chip PDN by combining full-wave simulation and de-embedding testing
To extract impedance parameters of advanced reduced instruction set computing machines(ARM)chip power distribution network(PDN)with unknown internal circuits and material information,an extraction method for the impedance of ARM chip PDN was proposed by combining full-wave simulation and de-embed-ding testing.First,the impedance testing fixtures for ARM chip PDN were designed.Then,S parameters of the impedance testing fixtures were obtained based on full-wave simulation.Subsequently,the impedance of ARM chip PDN was tested using de-embedding testing and an equivalent circuit model was established.Final-ly,the equivalent circuit model was verified using a digital control circuit application board.The results indi-cate that the resonant frequencies of the impedance curves obtained by simulation and testing are 56.34 and 57.37 MHz,respectively.There is good consistency between the simulation and testing impedance curves in the frequency band of 10 to 1 000 MHz.Therefore,this method can accurately extract the impedance parame-ters of electronic components of surface mounted devices.
