Similar to the border trap capacitance at low-frequency C-V curves, additional recombined charge per cycle at low-frequency charge pumping measurements could be attributed to the repetitive recombination of majority and minority carriers which instantly tunnel into and out of the border traps located near the high-k/oxide interface.

如同在低频电容—电压图形中的边界缺陷电容值一般，在低频电荷泵浦方法中所量测到的额外每单位循环再结合电荷载子数目，皆可归因於反覆的多数与少数载子再结合，而此一现象主要发生於高介电常数介电层/二氧化矽氧化层介面附近的边界缺陷。

A charge pump phase locked loop based on self biased technique is presented. In this technique, the operating bias levels are essentially established by the operating frequency of the voltage controlled oscillator, namely, all bias voltages and currents are determined by VCO controlling voltage. Thus, a fixed damping factor and a fixed ratio of the bandwidth to operating frequency are obtained, which are defined by th...

给出了基于自偏置技术的电荷泵锁相环电路，压控振荡器的工作频率动态地建立了电路内部所有的偏置电压和电流，从而实现了固定衰减因子，固定环路带宽与工作频率之比，这二者由电容的比率决定，极大地实现了电路设计的工艺无关性，同时也得到了小的相位抖动，最后，对这种锁相环的稳定性进行了一定的分析。

Therefore,high performance PFD and CP is the necessity and guarantee for high performance frequency synthesizer.
