    Analog circuit model by Verilog -A/AMS or Verilog ?

    Philcorb, How a analog circuit can be modeled in Verilog-D? Is it possible?

    Matlab simulstion results in a waveform viewer

    I figured out simulink can export VCD file. However i could not find a way to export or look at the results on the fly. I welcom any comment.

    Matlab simulstion results in a waveform viewer

    Hello all, I'm running a matlab simulation, but looking at simulink "Scope" outputs very painful. Do you know any waveform viewer which can replace the "Scope"? Should I generate a text file, and import it into a waveform viewer (e.g. synopsys comso scope)? If I can check the waveform on...

    Simulink minimum maxium time step setting for VCO simulations.

    I think this is realted to the sampling theory. I think the orginal source code was written with consideration of FFT.

    Simulink minimum maxium time step setting for VCO simulations.

    Hello all, I received a source file of a pll simulation from my colleague. However, I'm not in the situation to ask him about the source codes and bug him. :) I understand this is tmin, tmax related setting for a VCO and PLL simulations. Please take a look. FFTpoints = 32*1024 Prime_Bin =...

    KVCO of maneatis delay cell

    Hello all, I have a question. I believe everybody knows about Maneatis's symetrical load based delay cell. My question is this. Let's assume you are building a VCO based on the delay cell to be used in a PLL. The control voltage is comming from the charge pump. The frequency of VCO is...

    What is VT/R reference circuit?

    Thank you Keith. Can you elaborate more? If you can point out a textbook or a paper which talk about VT/R reference, it will be very helpful.

    What is VT/R reference circuit?

    Hello all, I heard a word "VT/R reference". I have been googling like a few hours. I could not find a solid lead. If you know what will be the best paper to understand the concept of vt/r reference. Please let me know. Thank you, Newmedia

    Specifications for PLLs of highend microprocessors

    Hello all, I want to find out what are the specifications for PLLs of high-end microprocessors. Does anybody has a detailed specification for a PLL? If you can point out any papers or white papers, I will really appreciate it. Thank you.

    PLL design flow examples?

    Hello all, I know this is a repeated question without a definite answer, but I have to ask this again. Have you ever seen a example of PLL design flow with cadence or other cad tools? It does not matter whether it's based on Cadence SpectreRF or Synopsys HspiceRF. I know Cadence has "Noise...

    The best high speed I/O design book or tutorial?

    Hello all, I don't have not much knowledge about high speed I/O design. I have been searched Amazon to find a great reference or textbook. I had no luck. I wish it's more practical than textbook. For example, the book or tutorial have to go though a detailed example of high speed DRAM...
