Description
The 64-channel optical cochlear simulator enables independent control of laser diodes with high-precision current-regulated pulses. The integrated RISC-V based digital controller allows individual pulse patterns to be flexibly programmed for each channel in order to implement complex sequences and timings. For use in a Cochlear Implant with wireless power and data transmission, the digital part has specialized interfaces, that enable an efficient configuration and triggering. The output stages provide an adjustable amplitude of max. 120 mA at 3.6-5 V with a resolution of 6 bit. The design is optimized for high switching speed and achieves typical rise and fall times of approximately 30 ns.
