A Neural Stimulator Front-End with Arbitrary Pulse

📋 论文概要

该论文提出了一种用于神经刺激的前端电路，能够生成任意形状的脉冲，并具有高电压顺应性（>10V）和自适应电源功能。该设计在0.35µm HVCMOS工艺下仅占用0.05mm²面积，解决了现有植入式刺激器灵活性不足、输出电压范围受限的问题。

💡 主要创新点

• 实现了任意脉冲形状生成，可编程控制刺激波形，提高刺激灵活性。
• 采用自适应电源技术，根据负载需求动态调整供电电压，降低功耗。
• 在0.35µm HVCMOS工艺下实现了0.05mm²的小面积，适合高密度植入式阵列。

📄 原文摘要

vitro arrays reached more than 10000 sites [1], implantable systems, e.g. for retinal [2,3] or cortical stimulation [4], have not exceeded above 1600 [5] – which was achieved with a reduction to basic functionality and wireline control of rectangular stimulation pulses. In contrast, experiments prove that a higher degree of flexibility of stimulators is needed: high-impedance applications require more than 10V output compliance
