摘要：
A biomedical signal sensing circuit including a first and a second modulation unit, an amplifying unit, a first and a second demodulation unit is provided. The first modulation unit performs a first modulation operation to a first medical signal according to a first signal to generate a first modulation signal. The second modulation unit performs a second modulation operation to a second medical signal according to a second signal to generate a second modulation signal. The amplifying unit amplifies the first and second modulation signals, and add the amplified first and second modulation signals as a third modulation signal. The first demodulation unit performs a first demodulation operation to the third modulation signal according to the first signal to generate a first sensing signal. The second demodulation unit performs a second demodulation operation to the third modulation signal according to the second signal to generate a second sensing signal.一種生醫訊號感測電路，其包括第一及第二調變單元、放大單元、第一及第二解調變單元。第一調變單元依據第一訊號對第一生醫訊號進行第一調變操作以產生第一調變訊號。第二調變單元依據第二訊號對第二生醫訊號進行第二調變操作以產生第二調變訊號。放大單元放大第一及第二調變訊號，並疊加放大後的第一及第二調變訊號為第三調變訊號。第一解調變單元依據第一訊號對第三調變訊號進行第一解調變操作以產生第一感測訊號。第二解調變單元依據第二訊號對第三調變訊號進行第二解調變操作以產生第二感測訊號。
