摘　　要：以 4级频移键控为核心 ,设计了一种用于 FLEX编码的寻呼机调频中频接收电路。该电路的工作电压范围宽 ,可以显示接收信号强度。HSPICE模拟表明该设计电路具有低功耗、高可靠性和精确度高的特点。A FM/IF receiver system used in FLEX pager is designed. 4 level FSK circuit is emphasized. This system can indicate the received signal strength, and its operation voltage can be adjusted in very wide range. Simulation by HSPICE is performed and it shows that the circuit possesses the character of lower loss, high reliability and high accuracy.
