The sixth-order active Butterworth low-pass filter has been designed in 0.18 μm CMOS technology in this paper. The topology consists of three second-order filters. The second-order filter is designed by using the Sallen-Key topology containing two stage operational amplifier, two resistors and two capacitors. The designed filter has a maximum passband attenuation of 9.5217 mdB and a minimum stopband attenuation of 50 dB. The cutoff frequency is 52.3 kHz and the power consumption is 2.27 mW.
