A charge pump circuit for stable latching in of a PLL requires a zero net charge transfer from the charge pump (CP) into the low-pass loop filter (LF) during a reference cycle, in order to set a stable control voltage (V tune) for the voltage controlled oscillator (VCO). The charge ...

两篇论文都是该领域的经典,charge-pump电流是模拟锁相环系统的关键模块,影响PLL带内噪声,尤其是小数/参考杂散的大小。数字锁相环中该模块被TDC替代,TDC的精度与charge-pump的电流失配一样,决定了PLL的带内噪声。不过,近年来,大家又将注意力集中到了模拟锁相环或者混合结构的锁相环结构中,原因是数字锁相环的离散...
