A Wireless Neural Recording SoC and Implantable Microsystem Integration

Abstract

An integrated 4-channel wireless neural recording system architecture is proposed. The system was designed to detect extracellular activity potential in the brain. Highly power-efficient front-end signal processing, spike detector, analog-to-digital converter, on-chip power management system, and FSK transmitter are designed and implemented on 0.5 μm CMOS process.
