S. Surav Yilmaz, A. T. To la. Fifth Order Butterworth Low Pass Square-Root Domain Filter Design // Electronics and Electrical Engineering. - Kaunas: Technologija, 2011. - No. 9(115). - P. 55-58. In this study, two different fifth order square-root domain low pass Butterworth filters are designed. First filter is designed directly from fifth order transfer function. Second filter is obtained by cascading one first order and two second order filters. Both filters are designed by using state space synthesis method and constituted by current mirrors, square-root circuits, current sources and capacitors. Proposed filters are simulated by PSpice using 3V supply voltage and 0.35 mu m CMOS technology parameters. Both filters simulation results are compared..
