This paper presents the noise optimization of a novel switched-capacitor (SC) based neural interface architecture, and its circuit demonstration in a 0.13 [Formula see text] CMOS process. To reduce thermal noise folding ratio, and suppress kT/C noise, several noise optimization techniques are developed in the proposed architecture. First, is developed to block noise charge transfer from parasitic capacitors to amplifier output. #link# Second, one recording path-splitting scheme is proposed in the input sampling stage to selectively re
