Abstract

Problem statement: Filters are widely used in various applications including communications, electronics and biomedical engineering. The performance and size of the filter is of interest especially in chip implementation. A switched-capacitor low-pass filter was designed and simulated using a 0.18 μm 1P6M CMOS technology. Approach: This circuit design offered obvious advantages in increasing the stopband attenuation, reducing passband ripple and achieving accurate frequency response. Results: This circuit achieved 53 dB stop band attenuation, less than 0.1 dB passband ripple, a 5 KHz cut-off frequency, a 100 KHz stopband frequency and consumes 6 mW from a 2 V power supply. Conclusion: The proposed design is very suitable for the realization of analog signal processing blocks in complementary MOSFET integrated circuits.
