挑战

设计并开发了一种用于感应的ASIC ,可与隐形眼镜直接设置。可以通过 ASIC 进行数字化的 MEMS 传感器正在读取评估结果并将其传输回记录仪,该记录仪与使用负载调制技术为设备供电的射频链路相同。通过使用 0.35µm 工艺, Faststream可以在有限的功率预算内以低成本在单个芯片上集成功率捕获和调节、RF 信号、高线性度 ADC 和数字控制功能。

解决方案

Faststream Technologies 监管 Sensimed 的整个 ASIC 生命周期,包括不同批量生产的设计、原型设计、工业化和供应链。在制造过程中,凸块裸片直接连接到透镜内的铜迹线上,将其连接到天线和 MEMS 阵列。

使用这些过程,Faststream 可以在保持线圈天线的功率资源范围内感知对高 ENOB 过程的需求。
