Abstract:
1. A system for recording neural signals of a brain, the system comprising: a plurality of implantable electrode sensors placed in juxtaposition to one or more neural circuits for receiving at least one neural signal; an analog-to-time signal converter for converting the received neural signals to an asynchronous pulse-width-modulated signal, the analog-to-time signal converter comprising a low-noise amplifier configured to receive the neural signals and a comparator, wherein the comparator comprises a first input that receives the output of the low-noise amplifier and a second input that receives the output of a triangular waveform generator programmed with a predetermined frequency and directly compares the output of the triangular waveform generator to the output of the low-noise amplifier to generate the asynchronous pulse-width-modulated signal; and a radio frequency (RF) modulator for transmitting the asynchronous signal, the signal converter and the RF modulator designed to be implanted in a living being.
