Abstract This paper presents the design of a G-C fourth order butter worth low pass filter for ECG detection. Since the performance of the filter strongly depends on the basic building block of trans conductor cell, a low power, highly linear, pseudo differential trans conductor cell working at 0.5 V in 180nmNWELL CMOS technology is designed. The gain of the designed trans conductor cell is 57 dB and the power consumption is 15 nW. The low pass filter has pass band gain 0 dB and cut off frequency of 250 Hz is designed. The total power consumption s 157.5 nW. Top Keywords ECG signal, EMG, Notch filter, Operational Trans Conductance Amplifier (OTA), Biomedical. Top |
