本論文主要目的在設計與實現低雜訊及低耗能的CMOS多通道類比前端放大電路,可應用於各類微弱的生理訊號處理以及醫療儀器系統方面之應用。在生物醫學系統研究中,類比前端電路用於生物訊號之處理與調整,為不可或缺的重要元件。本研究藉著積體化的系統設計方法,以達成縮小體積、減少消耗功率、降低成本以及增進使用方便為目的。本研究完成類比前端生理訊號放大器各個部份的電路設計、模擬、佈局、下線製作以及系統實現。最終實際的量測結果證實此架構之生理訊號放大器,可完全符合生理訊號量測之需要。
In this paper, we present a low-power, low-noise CMOS differential difference instrumentation amplifier (DDA) for MEMS physiological sensor applications. The MEMS sensor shows its great performance than standard wet electrodes and is suit for biopotential analog-front-end (AFE) sensing module integration. The fabricated 0.35μm CMOS AFE chip with 72μA power dissipation, 2μVrms input referred noise and 1.5V supply voltage acts correctly in actual ECG, EEG, EMG and neural signal measurements.
