Analog integrated circuit design for the wireless bio-signal transmission system

This paper presents an analog-signal processor chip design for its application on the wireless bio-signal transmission system. The processor is used to handle the physiological signal such as the electrocardiography (ECG), electroencephalography (EEG), or the electromyography (EMG), and so on. All analog blocks in the processor chip are realized in a 0.5 /spl mu/m double-poly and double-metal CMOS technology. The measured results show the processor chip can capture the bio-signal with the frequency range of 0.5 Hz to 220 Hz, and has a total voltage gain of 54 dB, good agreement has been found between computer simulation and measured performance. Compared to the on-board prototype system, on-chip processor system can minimize the hardware area and reduce the product cost.
