Abstract
An implantable EEG recording IC including 32 analog low noise amplifiers, band-pass filters, adjustable gain stages, and a 10 b SAR ADC is presented. The chip, implemented in 0.35 μm CMOS process, achieves 1.15 μVrms total noise in a 0.5-to-150 Hz band and consumes 22 μW from a 1 V supply, attaining a noise efficiency factor of 2.24.
