# noise analysis

• #### Noise sources in PSS analysis

Hi all, I have a pretty simple doubt. I am using Verilog A based circuit netlist to perform circuit simulation in cadence spectre. I have defined some flicker noise sources in the same netlist. If I simulated a simple differential amplifier, I can get the inut referred noise through noise analysis. Now...

• #### 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...

• #### New Book: Analog Design and Simulation Using OrCAD Capture and PSpice

Thousands of engineers worldwide use OrCAD Capture for PCB schematic entry and PSpice for circuit simulation. These popular products, both provided by Cadence, deserve a good "how to" book -- and now they have one. It's titled " Analog Design and Simulation Using OrCAD Capture and...

• #### noise analysis

Hello, After running noise analysis, printed noise summary. I couldnt understand te Param info from the summary. What is fn, id, rs etc stands for? Is the total input referred noise = total summarised noise/gain^2 ?

• #### Five-Minute Tutorial: Avoid SI Problems With Better Pin Placement In Encounter Digital Implementation (EDI)

I know we're over halfway through January already (where does the time go?), but Happy New Year everyone! I hope 2012 is a good one for your business and your chip designs, and let's hope the Mayans just ran out of ink when they were finishing the calendar for this year. Today I'd like to...

• #### How thermal noise of MOS can be made zero in spectre noise simulation(BSIM 4.6 Model)

I want to analysis contribution of flicker & thermal noise of complex circuit using spectre simulator separately. Also like to distinguish effect of each MOS contribution to whole circuit noise. Till now I succeed in nulling the effect of flicker noise by making its flag parameters to zero in model...

• #### Signoff-Driven Implementation = Consistent and Convergent = Predictable and Efficient

Digital designs are reaching 10's of millions of instances, which makes efficiency of the overall digital implementation and signoff flow critical to ensure predictability in the design schedule. A major stumbling block that can be a real threat to that predictability is iterations between different...
