摘要 设计了一种宽频率工作范围、可编程的频率合成器.引入自偏置的DLL结构及启动电路扩展系统频率范围,消除误锁定,在保证DLL系统稳定性及不改变系统锁定状态的基础上,实现倍频器倍频因子的随意转换.同时使用两位寄存器配置初始电压,保证系统的快速锁定.该频率合成器用0.13μm 1.8VCMOS工艺实现,工作频率范围为14~700MHz,可供选倍频数为1,2,4,8.在输入时钟为50MHz、倍频数为8、输出时钟频率为400MHz的工作频率下,系统功耗为28.44mW,周期抖动约为9.8ps. . A wide-range programmable frequency synthesizer is presented in this work. This frequency synthesizer uses self-biased DLL and a start-controlled circuit to enlarge the operating frequency range and eliminate harmonic locking problems. The programmable frequency-multiplied output can be quickly switched between xl, x2, x4 and x8 without affecting the lock state of the DLL. The Voltage Initial Selector is used to decrease the locking time. The proposed DLL frequency synthesizer, which has been realized in a CMOS 130- nm, can generate clock signal ranging from 14 to 700 MHz at 1.8 V supply. The total power dissipation is only 28.44 mW and the cycle-to-cycle jitter is about 9. 8-ps at 400 MHz.
