Description
BMD101 is NeuroSky’s 3generation bio-signal detection and processing SoC device. Device is designed with an advanced analog front-end circuitry and a flexible, powerful digital signal processing structure. It targets bio-signal inputs ranging from uV to mV level and deployed passes the raw signal through with NeuroSky proprietary algorithms.
The Low-Noise-Amplifier and ADC are the main components of the BMD101 analog front end. Because
of the BMD101’s extremely low system noise and programmable gain, it can detect bio -signals and convert them into digital words using a 16-bit high resolution ADC. The AFE also contains a sensor-off
detection circuit.
