A CMOS multichannel electrical stimulation prototype system

Abstract: SUMMARYWe developed an inductively powered integrated electronic prosthesis, allowing for the trade-offs among implant functionality, circuit complexity, power consumption, hardware cost, and integrity of data recovery, for a multichannel microstimulation circuitry. The proposed prosthesis features energy efficiency and is capable of up to 40 scan/s with 240 stimulus channels in mode I and three times resolution at the same scan rate in mode II under a carrier frequency of 2MHz. In order to satisfy future upgr… Show more

“…Also, the output voltage of the circuit is considered to be 1 V for a 1 kΩ load. The output power is considered to be in the range of mW because the proposed converter is designed for IMD applications such as retinal implants, cochlear implants, and invasive wireless neural recording systems where their power consumption is in this range . The simulated output in different process and temperature corner cases are illustrated in Figure .…”

“…In the technology‐filled and information‐filled lifestyles today, battery‐powered electronics are essential to everyone's life. From mobile learning devices to implantable biomedical monitor to remote sensors , the limited energy sources have been one of the most difficult design challenges for the circuit designers. On one hand, to provide fast‐responding performance, large biasing current is necessary.…”

“…Recently, Louis et al [19] have developed a multi-chip neurostimulator based on two-wire protocol for visual prosthesis, but the authors have generalized the application and considered electrode impedance up to 60 kΩ only. The design and implementation of a complete wireless microstimulation prototype for retinal prosthesis have been reported in [20] by Cihun et al The used electrode impedance by this system is only 10 kΩ.…”
