An Ultra-Low Power OTA-C Bandpass Filter Design for ECG Application

C. L. Hsiao and R. B. Huang
Abstract—An ultra-low power OTA-C bandpass filter is presented in this paper. An 1-150 Hz 4-th order OTC-C bandpass filter is design which is suitable for ECG application. A subthreshold region OTA is designed with current cancellation technology to achieve a very small transconductance. The OTA-C filter is design with TSMC 0.18μm CMOS process. The MIM capacitor is used in this design. The supply of the proposed circuit is 1V. The total power consumption is only 245nW.

Index Terms—OTA-C filter, ECG, low power, bioelectronics
