A fully integrated switched-capacitor filter design for ECG application

Abstract

A fully integrated switched-capacitor filter design is presented in this paper. The band-pass filter is composed by a high-pass and low pass filter. The passband of the filter is 0.05Hz-150Hz which is suited for ECG signal application. A notch filter is added in order to suppress the 60Hz induced noise. The switched capacitor technology is used to replace the large resistor. This circuit is design with TSMC 0.35μm process.
