This paper reports a 128-channel neural recording integrated circuit (IC) with on-the-fly spike feature extraction and wireless telemetry. The chip consists of eight 16-channel front-end recording blocks, spike detection and feature extraction digital signal processor (DSP), ultra wideband (UWB) transmitter, and on-chip bias generators. Each recording(More)
This paper presents the feasibility of applying an ultra-wideband (UWB) wireless scheme to both high data rate implantable neural recording and low data rate wearable biomedical applications. An extensive analysis on the UWB signal generation for biomedical application is discussed. A CMOS UWB transmitter has been designed, fabricated, and used in a high(More)
A neural recording system for monitoring the behavior of sharks is presented. The system consists of an II.ARCHITECTURE WITHOFF-CHIPADC electrode array made of silicon neuroprobes that interface with Figure 1 shows the multiplexed system architecture with a flexible parylene cable that connects the electrode array to off-chip ADC. The goal is to demonstrate(More)
This paper describes a low-power design of a ultra-wideband (UWB) transmitter for biomedical applications. The transmitter is the part of a telemetry unit that is being developed for a multi-channel neural recording system. The transmitter in the telemetry is intended to be attached or implanted in the body. Meanwhile an off-shelf receiver will be replaced(More)
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(More)
