摘要

神经肌肉组织电刺激已被证明可以治疗许多脊髓损伤相关的临床疾病，如运动功能恢复、癫痫治疗和其他生物医学应用。植入式电刺激器已经成为长期治疗和科学生物医学目的的有前途的解决方案。然而，设计这样的刺激器存在许多挑战。介绍了一种刺激效率高、片上面积小（0.0833 mm2）的植入式电刺激器集成电路。该器件能够提供高达800 μA的可编程刺激电流，负载阻抗为2.5 kΩ，同时保持线性。电源效率达到75.15%。当连接到较低的负载阻抗时，刺激器可以提供更高的电流。

Towards a high efficiency implantable electric simulator for programmable biomedical stimulations

Electrical stimulation of neuromuscular tissues has been proven to treat many spinal cord injury-related clinical disorders, such as motor function restoration, epilepsy treatment, and other biomedical applications. Implantable electrical stimulators have emerged as promising solutions for long-term therapeutic and scientific biomedical purposes. However, designing such stimulators presents many challenges. This paper introduces an integrated circuit for an implantable electrical stimulator with high stimulation efficiency and a small on-chip area of 0.0833 mm². The device is capable of delivering a programmable stimulation current of up to 800

μ

A to a load impedance of 2.5 k

Ω

while maintaining linearity. A power efficiency of 75.15% was achieved. The stimulator can deliver higher currents when connected to lower load impedances.

期刊介绍： The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
