A fully integrated CMOS super-regenerative wake-up receiver for EEG applications

A fully integrated super-regenerative wake-up receiver for wireless body area network applications is presented. The super-regeneration receiver is designed to receive OOK-modulated data from the base station. A low power waveform generator is adopted both to provide a quench signal for VCO and to provide a clock signal for the digital module. The receiver is manufactured in 0.18 μm CMOS process and the active area is 0.67 mm². It achieves a sensitivity of -80 dBm for 10^-3 BER with a data rate of 200 kbps. The power consumption of the super-regenerative wake-up receiver is about 2.16 mW.     

基于AVR的GPS轨迹记录系统

为了解决目前市场上出现的一些轨迹记录仪的缺陷,介绍了一种采用ATmega32的主控模块及与所述主控模块相连并受其控制的GPS接收模块、键盘模块、液晶显示模块、语音模块和电源模块的GPS轨迹记录系统。研发了适用性更好,功耗更低,功能更全面,续航能力更强,具有人性化设备,且能更快速精确记录各种轨迹的产品。经仪器检测以及实地试验表明,各项指标均已实现,误差也在精度允许的范围之内,有良好的实用价值。
