A rapid neural telemetry circuit (10) and system (100) for cochlear implants. The circuit (10) comprises a stimulus generator (110), a signal amplifier (120), an analog-digital converter (130), and a data calculation memory (140). The stimulus generator (110) is used for zeroing charges in nervous tissues at the beginning and before the end of the stimulus, and an interval between two continuous stimuli of a same electrode can be randomly adjusted. The signal amplifier (120) is used for carrying out filtering and amplification on a nervous impulse signal received by a collecting electrode and caused by electric stimulus. The analog-digital converter (130) can adjust the sampling frequency and the opening time delay, is connected to the signal amplifier (120) and is used for carrying out analog-digital conversion on an amplified analog signal. The data calculation memory (140) is connected to the analog-digital converter (130) and is used for calculating and storing data subjected to the analog-digital conversion. According to the rapid neural telemetry circuit and system for cochlear implants, the artifact of neural telemetry is reduced by improving a stimulation circuit, key parameters of the neural telemetry can be flexibly controlled, the neural telemetry leading-out rate is improved, and the data is calculated and stored so that the neural telemetry speed is extremely improved.L'invention concerne un circuit de télémétrie neurale rapide (10) et un système (100) pour des implants cochléaires.
