A 120pW 50Hz Notch Filter for Low-frequency Physiological Acquisition

摘要：

A CMOS OTA-C notch filter for 50Hz interference was presented in this paper. The OTAs were working in weak inversion region in order to achieve ultra low transconductance and power consumptions. The circuits were designed using SMIC mixed-signal 0.18μm 1P6M process. The post-annotated simulation indicated that an attenuation of 47.2dB for power line interference and a 120pW consumption. The design achieved a dynamic range of 7S.8dB and a THD of 0.1％, whilst the input signal was a 1 Hz 20mVpp sine wave.
