提出了一种一体化电池供电的低功耗 SoC，用于通过可穿戴设备测量多种生命体征。典型可穿戴用例场景所需的所有功能，包括专用读出器、电源管理电路、数字信号处理和无线通信 (BLE) 都集成在单个芯片中。这种高集成度实现了前所未有的小型化，从而减少了组件数量，从而降低了成本并提高了舒适度和信号完整性。该 SoC 包括 ECG、生物阻抗和全差分 PPG 读出器，并且可以与外部传感器（如 IMU）连接。在启用所有传感器读数且在芯片上计算关键功能（如心率）并通过无线电传输的典型应用场景中，SoC 仅消耗 1.2 V 稳压电源的 769 μW 功耗。
An all-in-one battery powered low-power SoC for measuring multiple vital signs with wearables is proposed. All functionality needed in a typical wearable use case scenario, including dedicated readouts, power management circuitry, digital signal processing and wireless communication (BLE) is integrated in a single die. This high level of integration allows an unprecedented level of miniaturization leading to smaller component count which reduces cost and improves comfort and signal integrity. The SoC includes an ECG, Bio-Impedance and a fully differential PPG readout and can interface with external sensors (like an IMU). In a typical application scenario where all sensor readouts are enabled and key features (like heart rate) are calculated on the chip and streamed over the radio, the SoC consumes only 769 μW from the regulated 1.2 V supply.
