high-speed时,PVT也会影响valid window,导致valid window直接为0 所以为了解决上述问题,rambus于1990s,提出了DLL(delay lock loops)与PLL(phase lock loops)概念 DLL和PLL可以保持信号之间的时序关系,主要通过连续比较两个信号之间的关系不断反馈调整他们之间的固定关系来工作 mimic--模仿 DLL可以保持clock与输出数据信...

A delay locked loop circuit comprising: receiving means for receiving a system clock signal and outputting a first clock signal; delay locked loop, so that the receiving delay locked loop with a first clock signal synchronized with a phase detector; and an off chip driver circuit receiving a ...
Delay-lock loop control can ensure the in-phase operation of ac input voltage and current for high power factor (PF) and low total harmonic distortion (THD). In addition, redundant power loss in Triac dimming control is eliminated to get a high efficiency of 85%. Furthermore, a high PF ...
A solution to the mean time to lose lock for a first order, pseudo-noise, code tracking loop is derived for both the fulltime delay-lock loop and the time-shared delay lock loop, with both utilizing an early-late gate size of 1/2 chip, and assuming ideal bandpass filters. The result...
If the measurements of the EKF are more than four, then the variance of the dynamic stress error and oscillator noise error will be decreased which is similar to a vector delay lock loop (VDLL) [10, 11]. Improvement of Carrier Phase Tracking Based on a Joint Vector Architecture Townsend,...
