In order to design a effective EMI filter, noise source impedance (complex impedance) is very crucial, but actually, the result is low accuracy and no phase by employing traditional approaches. In the paper, a modified EMI noise source impedance modeling is proposed to investigate the characterization of EMI source impedance. The test shows that suggested method is more accurate and effective. Moreover,...
This paper studied the effects of thin-film ferroelectrics as decoupling capacitors for electromagnetic compatibility applications. The impedance and insertion loss of PZT capacitors were measured and compared with the results from commercial off-the-shelf capacitors. An equivalent circuit model was extracted from the experimental results, and a considerable series resistance was found to exist in...
