Abstract

With the need of researching brain-computer interface (BCI), it is very important to design an ASIC for detecting EEG signal. The main blocks of the EEG acquisition chip includes one chopper-stabilized differential difference amplifier, low-pass filter, gain amplifier, non-overlapping clock generator, and band-gap voltage reference circuit etc. All the circuits have simulated by the Cadence Spectre. Full custom design flow has been used in this research, and using 0.6um CSMC DPDM CMOS technology.
