# phase noise

• #### Re: Phase Noise vs frequency graph problem

Hello Frank, Really appreciate your help..I have put my latest schematic in this post..if you have time to have a look...I haven't used the oscillator mode in pss analysis.. I have a few other problems too which i will be posting separately.. I am having trouble getting quadrature output..i.e. the...

• #### Re: RE: Phase Noise vs frequency graph problem

Hello Tawna, I am very thankful for your reply...Read a lot of posts by you and Andrew in various topics and a fan of your knowledge and work.. I got the correct graph yesterday when I changed errpreset to 'moderate' and putting tstab as 60n..but the values of phase noise was aroung -140dbc/hz...

• #### Re: Phase Noise vs frequency graph problem

Thanks Frank for replying. Yes, I have seen that post-it explains the equation which spectre uses to find the pnoise...but it doesnt help me to get the right graph with negative values of pn. I am doing the pss-pnoise simulation using the following settings: PSS : Harmonic Balance beat freq - 37.93G...

• #### Phase Noise vs frequency graph problem

Hello I am a newbie engineer starting my career in IC design and working on a high frequency oscillator (38 GHz). I am using Cadence IC6.1.5-64b.500 version and using spectre simulator for the schemtic design and simulations. I am having doubts about my 'pnoise' analysis. All the research papers...

• #### Transient noise

Hi , What does the transient noise tab in the analyses window of spectre means and what were the values should be given for noise max. ,noise min and bins if my oscillator is working at 450MHzand running for 150ns. Thanks in advance. with regards, Jithin

• #### 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...

• #### Q&A: TI Wireless Team Describes Advanced Phase-Noise Characterization for RF Oscillators Using SpectreRF

In this interview, members of the Texas Instrument wireless group talk about the characterization effort initiated and completed last year between Cadence and IBM using TI RF designs as a pilot. The goal between the two teams was to optimize SpectreRF usage to successfully and efficiently simulate TI...

• #### Jitter in Strong and Weak Inversions

Dear all, I have designed a crystal oscillator, but some doubts still remain. Below please find the schematic attached (Pierce Oscillator). 1 - When analysing the phase noise a "bump" appears by the end of the curve (both in strong and weak inversion). What is the reason for that (file attached...
