Abstract: A low power low frequency active-RC filter for ECG detection is presented. A folded cascode Operational Transcon-ductance Amplifier (OTA) with transistors operating in sub-threshold region at 1.2 V supply voltage is designed in 180 nm CMOS process which consumes a power of 30 nW. A second order low pass filter with a cut-off frequency of 50 Hz is built with the designed OTA. To achieve this low bandwidth, current steering technique is used instead of traditional method of using large resistor and capacitor values and hence the design is area efficient. The filter consumes a power of 80 nW, has a dynamic range of 49 dB and shows a figure of merit (FOM) of 0.4 pJ/pole. © 2019 IEEE.
