 Abstract—The dual-band recording of the local-field potential (LFP, 0.1Hz~200Hz) and the spike potential (SP, 200Hz~10kHz) is important for physiological studies at the cellular level. Recent study shows that the LFP signal plays important roles in modulating many profound cellular mechanisms. Although various bio-signal acquisition circuits have been(More)
Cellular field potential includes local field potential (LFP, 0.1Hz∼200Hz) and spike potential (SP, 200Hz∼10kHz). SP signal has been the focus of physiological studies. Recent study shows that the LFP signal plays important roles in modulating many profound cellular mechanisms. Although many bio-signal acquisition circuits have been reported(More)
So far almost all wide-band (>10MHz) continuous-time ΣΔ ADCs use active-RC filters. Although this type of filter possesses excellent linearity, it behaves as a resistive load for the preceding stage, which requires a signal buffer. For high speed and high resolution applications, a low noise and low distortion signal buffer consumes quite(More)
