本文提出了一种便携式无线传感器系统的生物医学和环境应用。所提出的系统将模拟前端传感器、处理、存储器和无线通信集成在单个芯片上，允许便携式、可穿戴或植入式使用。在这项工作中提出的电路包括一个pH值频率传感器，阻抗频率传感器，蓝牙接收器前端，和一个8位MIPS处理器。所有电路都采用标准的180 nm CMOS技术在同一芯片上制造。总芯片面积为0.332 mm2，总功率为4.75 mW。
This paper presents a portable wireless sensor system for biomedical and environmental applications. The proposed system combines analog front end sensors, processing, memory, and wireless communications integrated on a single chip, allowing for portable, wearable, or implantable use. The circuits presented in this work include a pH to frequency sensor, an impedance to frequency sensor, a Bluetooth receiver front-end, and an 8-bit MIPS processor. All circuits are fabricated on the same chip using a standard 180 nm CMOS technology. Total chip area is 0.332 mm2 and total power is 4.75 mW.
