Unlike Nehalem/Gulftown architectures, Sandybridge can benefit from a small increase to PLL voltage when running higher CPU multiplier ratios (hence CPU core frequency). As always, caution is advised with regards to over-voltage on this rail – personally I don’t use any more than 1.85V and...
The frequency modulation circuit can be made up of a phase-locked loop, as can be seen. The illustration depicts a block diagram of a frequency-modulation circuit made up of a phase-locked loop. The block diagram of the demodulation circuit is illustrated in Figure 3, and it is based on...
We describe a very simple clock multiplier circuit, capable of multiplying the clock frequency by an integer M and producing an output with a relatively symmetric, self-adjusting phase. The circuit is not PLL- nor DLL-based, and feedback loops are not utilized. However, contrary to PLL or ...
This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume more power per cell than their ...
The dual-polarization Twin PLL integrated circuit dual-output frequency demultiplier has the advantages that functions are practical and variable, output frequency is stable, and the structure is simple.姜晧文
control circuit that's both frequency- and phase-sensitive. A PLL is not a single component, but a system that consists of both analog and digital components -- interconnected in a "negative feedback" configuration. Consider it analogous to an elaborate operational amp (op amp)-basedamplifier...
