phase noise simulation

  • Group noise contributors

    Hi guys, When you do print->noise summary after a noise sim or pnoise sim, is there a way to group noise sources together; either by block or device? In the case of an extracted list, if you have a number of fingers for a transistor, the noise simulation gets broken down into each individual finger...

  • PN function in Visualizaion & Anaysis XL Calculator

    Hi, I have a question about the PN function, available in the Calculator. Is an output phase noise spectrum is a signle sideband or a double sideband spectrum? To avoid any confusions, I mean the 'double sideband' by a spectrum 3dB more than the 'single sideband' in magnitude. Thanks...

  • VCO: PSS and pnoise analysis and Numerical Errors

    Hello, I am Sivaramakrishna. My query is about the numerical/simulation errors in pnoise/pss analysis of VCO. I am designing a (CMOS LC-) VCO and Interesting I am getting different phase-noise for the same circuit with with same settings, such as initial conditions, and integration methods(it was suggested...

  • phase noise of divider

    I need to simulate the phase noise of a divider (or, more generally, simulate the phase noise on a non-sinusoidal signal). Most straightforward way is SpectreRF -> pss -> pnoise. There used to be a Cadence application Note about how to do this. I remember it had to do with simulating pnoise with...

  • pnoise jitter noise contribution

    hi, i am running pss and pnoise on a driven circuit using noisetype=jitter this simulation provide me the integrated rms jitter. Question1: How can i find out the individual noise contributor in this simulation? I ask because i read somewhere on the help manual that noise seperation can only be done...

  • Insufficient memory in PNOISE simulation

    I'm trying to do phase noise analysis with PSS HB and PNOISE for post layout extracted netlist. I got the following error: Mem Used: 12813.8 MB (Memory Exhausted) Fatal error found by spectre at freq = 10 MHz during PNoise analysis `pnoise'. FATAL (CMI-2002): Insufficient memory available. To...

  • Jitter from pnoise simulation

    I'm desinnig a Time to digital converter and I would like to simulate the jitter of a driven buffer having a rising time of 350 ps. In my schematic, the buffer is driven by vpulse (ideal CLK @ 2 MHz) and I would like to simulate his output jitter. My setting of pss simulation is as follow: Beat frequency...

  • Cadence noise aware PLL design flow: have lock problem

    Hi All, It is a bit long story. I will try my best to explain it clear. Thanks for your patience to read it through and give me some feedback. Recently I tried to follow Cadence noise-aware PLL design flow (PLL Macro Model Wizard) to verify my design. (We got the PLL_workshop from Cadence already) I...

  • Noise separation in phase noise simulation

    Hello, I'm doing a phase noise simulation in cadence (using MMSIM70) and I'm using the option "noise separation" to determine the amount of noise introduced by each instance in my circuit. However, when i compare the total output noise (in the band of interest) with the sum of the individual...
