Hi all Lately, cadence provide the PLL designer with a good tool named noise-Aware PLL Flow. I have succeed to extract the PFDCP and VCO macro and its noise. However, when I run the overall pll bench, there is no PLL noise PSD Data to plot though the PLL is locked properly in the transient simulation. Your answer is (...)
Hi, I would like to do the flicker noise(1/f noise) simulation of differential opamp using cadence tool. Which analysis I should do? Is it noise , pnoise or pss analysis? How to give the necessary parameters for these analysis? Do anyone have an example schematic for noise (...)
I have taken phase noise data from cadence and plotted it in Matlab, but when I add datacursors the values are written in scientific notation, i.e. 300kHz is written as 3.000e005 Hz. I've modified the code for datatip display a little bit myself just to show the units, but other than that I don't know what to do. this is my code: pos = get
How to do noise analysis i mean setup we do. I am using the cadence tools.
Hello, I want simulate my first first order delta sigma ADC, attached schematic. I can simulate it and I see behind the LP again my input signal. My problem is I cant see the noise shift to higher frequency. I simulate transient and adjust transient noise (noisefmin noisefmax and noisescale) measure (...)
Hi evrybody; I have a question, How Simulate noise in bandgap circuit? i'm using cadence "Spectre" I'm inexperimented please step by step Thanks Regards .
any suggestion? thanks
It is very diffucult to simulate the PLL in cadence system expecially for the case of high N value. Instead, you can use verilog-A to model the VCO with its phase noise and to model other components. Then simulate PLL, it will be good. But you need to make sure your modeling is correlated to real circuit. For phase noise modeling, (...)
I don't know what cdb is cdb is the cadence database format. There is slew information in cell characterization of cdb libraries. I'm not sure how it works. See if you can glean anything from this sourcelink post: questions on cdb noise library characterization Error Message: None Problem statement: For librar
hey does ne1 hav cadence virtouso help manual regarding how to do various digi n analog analysis lyk delay, power,pdp,min n max vdd,noise ,rms value,capacitance,....................n al that. plzzzz its urgent!!
1. Are there any ideas how to perform SNA (substrate noise analysis) in cadence? Does the SNA a part of Assura package or a separate one? What is its relations with technological processes, maybe special control (rule) files? Any relevant links are welcomed. 2. Are there any tools from Mentor for a such type of analysis? Thanks in advanc
:?: Could you anybody recommend me software tools (preferably from cadence) to be used for substrate noise analysis. Are there any tutorials on them? Thanks.
Hello all When i do pnoise of a charge pump of a pll, the output is dBc/Hz so, it is normalized to the carrier, right? What is the carrier here? i understand this simulation for oscillators as there is a sinsoid carrier i normalized w.r.t. it but for charge pump what is the carrier??????? MohamedAbouzied
Hello, Why for Charge Pump they do Phase noise analysis "pnoise in cadence"?? As i understand, this simulation for oscillators. and charge pump doesn't oscillate. also, after this simulation, i generates dBc/Hz and dBc is dB carrier, What is the carrier in this case? Thanx a lot MohamedAbouzied
How to simulate pop noise in cadence? Thanks a lot.
Hi, Can anyone upload or where can i find the reference material about the cadence pole/zero analysis and noise analysis? Thanks a lot!
hii, How to plot LO feed through at RF port and IF port for a mixer in cadence? Thanks..... Just observe RF port and IF port in PSS with LO large signal. About cadence tool, you had better post in the following.
Hi, How to plot the conversion gain,noise figure and others with temperature variations in spectre.......please help me..... Thanks in advance......
Hi, I need to find the input referred noise of a folded cascode amplifier in cadence. please help me. any material would also do . thanks
cadence can do this too using the cells in lib "pllLib"
