A 14-ENOB Delta-Sigma-Based Readout Architecture for ECoG Recording Systems.
IEEE Transactions on Circuits and Systems I: Regular Papers(2018)
摘要
This paper presents a delta-sigma based readout architecture targeting electrocortical recording in brain stimulation applications. The proposed architecture can accurately record a peak input signal up to 240 mV in a power-efficient manner without saturating or employing offset rejection techniques. The readout architecture consists of a delta-sigma modulator with an embedded analog front-end. Th...
