noise figure

  • Re: RF Front end Receiver

    Hi Kiran1507, If you are using MMSIM12.1.1 or 13.1, I recommend looking at Appendix A of the SpectreRF User Guide. There are a number of step by step examples that you may find useful. Please note: To run the examples, you will need to obtain the gpdk180 PDK from http://support.cadence.com (it is no...

  • RF Front end Receiver

    Hi, We are designing a RF Front end receiver in which we are proceeding with a PSS, PAC, etc analyses..... 1. We have plotted Conversion Gain Vs LO power by doing PSS followed by PAC analyses. So, can we plot the same CG by varying RF. 2. Can we plot Noise Figure Vs RF frequency. Please, get me the valuable...

  • Re: Noise Figure of an upconverting mixer under input IF signal

    I recommend taking a look at the Appendix A of the SpectreRF User Guide (version 12.1.1 or later). There is a more thorough and up to date example of simulating a transmit mixer. Please use that instead. Here is the link to the appendix. http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:DocumentViewer;src...

  • 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...

  • 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...

  • Noise Figure discrepancies in LNA design

    This question is regarding noise figure in a simple common-emitter LNA in the W-Band. There are two main simulations that I am using: A) sp analysis with noise set to "yes" and the input/output ports specified. B) noise analysis with the input port specified, and the output specified as a voltage...
