| 中文摘要 | a monolithically integrated cmos bioamplifier is presented in this paper for eeg recording applications. the capacitive-coupled circuit input structure is utilized to eliminate the large and random dc offsets existing in the electrode-tissue interface. diode-connected nmos transistors with negative voltage between gate and source are candidates for large resistors necessary to the bioamplifier. a passive bef (band eliminator filter) can reduce 50 hz noise disturbance strength by more than 60 db. a novel analysis approach is given to help determine the noise power spectral density. simulation results show that the two-stage cmos bioamplifier in a closed-loop capacitive feedback configuration,provides an ac in-band gain of 39.6 db, a dc gain of zero, and an input-referred noise of 87 nvrms integrated from 0.01 hz to 100 hz. |
