摘要：
This paper presents a 4-channel wearable wireless neural recording system that consists of wireless head stage, receiver board, and user interface software. The wireless head stage is implemented using a custom designed font-end IC for bio potential amplification, filtering, and channel selection and a commercial analog FM transmitter chip. Adjustable gain and bandwidth of the channel allows the system to be used in recording various neural signals. The size of the head stage is 1.55" x 1.725" x 0.5" and the weight is 20g. The power consumption of the head stage is 28mW from two 1.55V button cell batteries that allows continuous operation of at least 15 hours. The system was tested for ex-vivo and in-vivo extracellular recordings from a dissected snail brain and a live rat respectively.
