PSS

  • Re: Nport Component (S-Parameter Files) in PSS Analysis

    Hi Frank, just to clarify... Linear and spline interpolation methods are supported in pss-hb and hb (and all subsequent small signal analyses) and envlp. pss-shooting can be used with the nport in some circumstances. Linear and spline interpolation methods are not supported for Shooting QPSS/QPXX, Shooting...

  • Phase noise plot

    Hi, I have been doing a Pnoise analysis . Unfortunately I was unable to plot the phase noise response. My design was setup was described below. My apparatus was a PLL with a fixed divider ratio of 20 and output frequency of 500Mz In PSS analysis I have set the beat frequency as reference frequency ie...

  • Pnoise analysis

    Hi, I have been designing a PLL which gives an output frequency in the range (400-500)MHz to the reference input frequency of (20-25)MHz.So for doing the pnoise analysis I have added the PSS as well as Pnoise analysis I have made the following as setup for the analysis for a frequency of 500MHz. I have...

  • No Insufficient Memory Promble in PSS/Pnoise simulation

    Hi, I have some promblems on VCO Post-simulation of PSS and Pnoise. The Frequency of the VCO is 20GHz. When I simulate the schematic, everything is good. But when I comes to Post-simulation, there will always be the error "no insufficient memory". At first, I can't finish the pss and one...

  • How to simulate the Noise figure in Pnoise from 1 stage to another?

    Hi there, I want to simulate the Noise figure for such a setup that first a band pass filter, then sample and hold, and then follower by amplifier, and ADC and so on. Can i get the noise figure from source to each stage with Pnoise? I understand that if the output is specified with voltage of two node...

  • PSS Analysis's reliability-Difference between time domain response in PSS and Tran analysis

    I'm designing a wide band matching network to drive an antenna.The output pulse at the output of pulse generator is delivered to one N1PORT as the antenna model thet refered to a S1P file with value from 1GHz to 8GHz. I want to use this interface between antenna(S1P port with n1port component) and...

  • High frequency quadrature VCO design with good phase noise

    Hello everyone I am a newbie engineer starting my career in RF IC design and working on designing a high frequency VCO (38 GHz) with good phase noise characteristics. I am using Cadence IC6.1.5-64b.500 version and spectre simulator for the schemtic design and simulations. I have to do everything from...

  • PSS analysis - oscillator

    Dear all, I am simulating an oscillator (RLC lumped element connected to a sustaining amplifier) in SpectreRF 5.10.41.121508. The oscillation frequency is about 0.85 MHz. There is some initial current condition (50nA) for the inductance L. The transient analysis runs well and shows the oscillations building...

  • 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...
