摘　　要：针对无线接收器功耗影响无线传感器网络生命周期的问题,在OOK超再生接收器的基础上,设计了一种无线传感器网络超低功耗无线接收器——BFSK超再生接收器;介绍了该接收器的体系结构,给出了该接收器的电路设计。该接收器在保留OOK超再生接收器超低功耗的基础上,采用f1和f2两种频道来确定输出是"0"还是"1",使得传输速率得到了较大提高。实验结果表明,当传输速率为250kbit/s时,2.4GHz接收器灵敏度为-86dB.m,功耗仅为215μW。In view of problem of influence of power consumption of wireless receiver on lifecycle of wireless sensor network, BFSK super-regenerative receiver, namely a wireless receiver with ultra-low power consumption for wireless sensor network was designed based on OOK super-regenerative receiver. Structure and circuit design of the receiver were introduced. The super-regenerative receiver employs two channels of f~ and f2 to determine output if ＂0＂ or ＂1＂ based on reserving ultra-low power consumption of OOK, and greatly improves transmission rate. The experimental results show that the sensitivity of 2.4 GHz receiver is --86 dB.m and the power consumption is only 215 #W when its transmission rate is 250 kbit/s.
