In this paper, Elliptical Low pass filter working at GSM band is realized using multilayer fractal spiral inductor and fractal spiral capacitor based 0.18 μm process. Multilayer fractal inductor and fractal spiral capacitor is shown to have good Q factor values. The influence of fractal passive components on the insertion loss of low pass filter is analyzed by EM simulations. The designed 3.17nH multilayer inductor has a maximum Q of 30 @ 6 GHz and the realized LPF GSM/AMPS band has the insertion loss of 0.4dB and return loss of more than 15dB in the passband.
