    Analog PLL or Digital PLL

    ADPLL I mean a divider less, TDC based design that all the blocks are digital except the oscillator which is analog but is controlled digitally (digital controlled oscillator).

    Analog PLL or Digital PLL

    But there are many ADPLL structures that use also LC-tank. In this case, what are the advantages of analog PLL?

    Analog PLL or Digital PLL

    Hello, many advantages are mentioned in the papers related to Digital PLL but I see also many designs that still use Analog PLL. Can anybody help me to know that why still analog PLLs are popular and what are their advantages? Thanks

    [Moved]: Phase noise modeling of the digital controlled oscillator

    Hello, I have a basic question about the noise simulation for the digital controlled oscillator in matlab. There is two profiles for the phase noise as the attached figures. One (left side) is obtained by importing the phase noise at different offsets to matlab. The other (right side) is...

    Frequency of a random pulse over time in simulink

    Actually I found the way. I used a resetable counter which is sampled by a dflip flop at the output.

    Digital phase locked loop adder

    Hello I should implement a proportional- integrator loop filter. in the integral part, there is one accumulator which I implement using full adder as in the picture. there is 6 bits at the inputs of full adder and the output with carry is 7 bit. But it seems that here the carry is ignored, does...

    [Moved]: Digital phase locked loop

    Hello, I want to learn about digital phase locked loop design. As far as I search, there are implementation about it in some thesis or articles which explain their main blocks like TDC, DCO,... I understannd their concepts but I have problem about the interface to connect this blocks. for...
