In general, there are two design rules that should be followed when using an active loop filter implementation. First, the output of the charge pump should always feed directly into a high-Q capacitor (i.e. a capacitor with minimal series resistance) in order to attenuate its high frequency ...

向是PLL，之所以比通常研二上学期才定毕设方向要早半学期，是因为老师和我都知道对于现在 自身的基础以及这边实验室能提供的条件都有限，所以希望我自己早点选定方向，早点开始。对于选择方向，是在去年年底就开始考虑了，权衡了自己导师的生物医学芯片的难度和自己的 兴趣，最后还是决定选自己感兴趣的射频方向，以及综合...

Referring to FIGS. 6-7, methodologies for calibrating the loop bandwidth of a phase-locked loop are illustrated. While, for purposes of simplicity of explanation, the methodologies are shown and described as a series of acts, it is to be understood and appreciated that the methodologies are not...
All crystals have a series and parallel resonant mode and the mode of oscillation depends how the crystal is hooked up in the circuit. The value of Rs has only a very slight impact on the oscillation frequency. However, it does impact how sharp the cutoff is, which corresponds to the ...
