IP명 A Bidirectional Neural Interface Analog Front-End IC for Implantable Medical Devices Using Standard CMOS Technology
Category Analog Application biomedical IC
실설계면적 3.8㎛ X 3.8㎛ 공급 전압 1, 1.8, 3.2V
IP유형 Hard IP 동작속도 250kHz
검증단계 Silicon 참여공정 MS180-1902
IP개요 This work presents the design of a bidirectional neural interface analog front-end IC for implantable medical devices using 0.18-µm CMOS process. The implemented analog front-end IC is comprised of a biphasic bipolar neural stimulator with a novel charge-balancing architecture which can accurately deliver up to 1 mA of current to the high impedance electrode-tissue interface, and an ultra-low-power low-noise neural recorder which can process both action potential and local field potential signals in the band of 1 Hz to 10 kHz. The recording path is comprised of low-noise neural amplifier, programmable gain amplifier with tunable filter, and a 10-bit SAR ADC.
