A 500µW Neural Tag with 2µVrms AFE and Frequency-Multiplying MICS/ISM FSK Transmitter

📋 论文概要

该论文提出了一种功耗仅500µW的神经标签芯片，集成了2µVrms噪声的模拟前端和频率倍增的MICS/ISM频段FSK发射器，用于短距离神经接口通信。解决了神经记录系统中低功耗、低噪声和高能效无线传输的挑战。

💡 主要创新点

• 采用频率倍增技术实现MICS/ISM频段的FSK发射，在极低功耗下实现高效无线传输。
• 模拟前端达到2µVrms的低输入噪声，同时整体功耗仅500µW，适合植入式神经记录。
