Problems solved by technology

[0003] In the prior art, the reverse signal transmission and receiving function is set in the speech processor, which is built with discrete components. The transmitting coil receives the feedback signal from the implant parts from the receiving coil and then transmits it to the speech processor through wires, so that the RF signal The impact is great, and for applications where the speech processor and the transmitting coil need to be far away, it is difficult to achieve the expected signal transmission effect. The transmission of the reverse signal through the wire may form a closed-loop feedback, and the signal will become larger and larger, resulting in the final cochlear implants not working

Abstract

The invention discloses an electrical cochlea reverse signal radio frequency transmission receiving chip and system. The electrical cochlea reverse signal radio frequency transmission receiving chip comprises a detector circuit, an amplifying circuit, an analog-digital conversion circuit and an emission preprocessing circuit. The detector circuit is used for carrying out rectification on received input signals. The amplifying circuit is used for carrying out smoothing and amplifying on detecting-output signals. The analog-digital conversion circuit is used for converting the smoothed and amplified signals into digital signals and outputting phase-opposite digital signals. The emission preprocessing circuit is used for setting the initial state of the amplifying circuit. The electrical cochlea reverse signal radio frequency transmission receiving chip and system are high in sensitivity, high in reliability, high in stability and high in integration, the whole electrical cochlea system can be reliable, electricity is saved, and size is small.

Description

technical field [0001] The invention belongs to the field of cochlear electronics, in particular to a cochlear electronic reverse signal radio frequency transmission and receiving chip and system. Background technique [0002] As we all know, cochlear implants mainly include external machine parts and implant parts implanted in the human brain. figure 1 A schematic diagram of the structure of the cochlear implant is shown. Its working principle is that the speech processor in the external machine part processes and codes the sound signal from the microphone, and after obtaining the coded signal, it passes through the transmitting coil and transmits it through the skin to the receiving coil of the implanted device, and then implants the body part The decoding circuit decodes and obtains the decoded signal, and transmits the decoded signal to the electrode array of the cochlear implant to stimulate the user's auditory nerve and restore the user's hearing. [0003] In the pri...
