工作展示了一款采用标准CMOS工艺技术的9V无线电力和数据接收IC。该IC采用了晶体管堆叠方案，以适应超过晶体管电压容限的高压域中的有源电路。通过交错耦合整流器，该IC成功生成9V电压，并通过低压差稳压器（LDO）提供了6V和3V的稳压电源，最大功率输出为27mW，峰值功率转换效率（PCE）为74.2%。基于开关键控（OOK）和负载移位键控（LSK）调制方案，分别实现了200kbit/s的正向遥测和10kbit/s的反向遥测。该IC可作为无需电池且需要高电压的医疗植入物的无线电力解决方案。
This work presents a 9-V wireless power and data receiver IC in a standard CMOS process technology. A transistor-stacking scheme is employed for accommodating active circuits in a high-voltage domain that exceeds the transistor’s voltage tolerance. The IC successfully generates 9-V through a 21-stage cross-coupled rectifier and regulated 6-V and 3-V supplies with LDOs delivering a maximum power of 27 mW with a peak power conversion efficiency (PCE) of 74.2%. Forward telemetry at 200 kbit/s and backward telemetry at 10 kbit/s are achieved based on on-off keying (OOK) and load-shift keying (LSK) modulation schemes, respectively, which negligibly affect the generated voltage domains. The IC serves as a wireless power solution for battery-less and high-voltage-required medical implants.
