摘要

本文提出了一种全集成开关电容滤波器的设计方案。带通滤波器由高通和低通滤波器组成。滤波器通频带为0.05Hz-150Hz，适合心电信号应用。为了抑制60Hz的诱导噪声，增加了陷波滤波器。采用开关电容技术代替大电阻。本电路采用台积电0.35μm工艺设计。

A fully integrated switched-capacitor filter design for ECG application

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.
