Abstract

Low power consumption and small size transceivers are critical for biomedical instruments and devices specially those that are implanted. In this paper a novel modulation scheme called saturated analog signal (SAS) has been developed that can reduce the power consumption and area of the receiver. The new CMOS receiver is implemented in 65nm technology and operates in the MICS band (402–405 MHz), while consumes 10 µW from a 1 V power supply to deliver 500 Kb/s of data and occupies an area of just 0.6 mm2. This is equivalent to an energy consumption of 20 pJ/b and the design is capable of being fully integrated on single chip solutions for retinal prosthesis and embedded neural applications.
一种基于新型调制(SAS)的20 pJ/b(10µW)数字接收机用于视网膜假体应用
低功耗和小尺寸收发器对于生物医学仪器和设备,特别是那些植入的仪器和设备至关重要。本文提出了一种新型的饱和模拟信号(SAS)调制方案,该方案可以降低接收机的功耗和面积。新的CMOS接收器采用65nm技术,工作在MICS频段(402-405 MHz),在1 V电源下消耗10 μ W,传输500 Kb/s的数据,占地面积仅为0.6 mm2。这相当于20 pJ/b的能量消耗,并且该设计能够完全集成在视网膜假体和嵌入式神经应用的单芯片解决方案上。
