本文在0.25μm CMOS工艺下设计实现了一种可用于STM-16标准时钟恢复电路的锁相环模块.在理论分析基础上
分别采用Alexander结构、改进型电流舵开关技术、Maneatis环形振荡器结构设计了锁相环模块中的鉴相器(PD)、电荷泵和压控振荡器电路
并完成了整个锁相环模块的优化.经Hspice仿真实验
设计实现的锁相环中心频率为2.5 025 GHz
在3.3V电源电压下的功耗为40 mW
环路带宽为60 MHz
锁定时间约为640 ns
满足性能设计需求
并具有低功耗、低电源电压、低噪声等特点
研究结果对于光纤通信系统、FM解调器、立体声解调器、声音检测器、频率分析仪和其他很多应用都要重要价值.
This paper achived a PLL module used in CRC based on STM-16 standard by using a 0.25μm CMOS technology
the PD used Alexander structure
the CP used a improved current-steering switch tech- nology.Maneatis ring oscillators are used as VCO.Hspice simulation results show that the circuit can work at 2.5025GHz
the power dissipated is 40mw under 3.3V supply.The results indicate that the main functions of the PLL module are realized and have practical value.
