Thermal Noise spectrum of a resistor

kenambo

HI..


  Is it possible to view the thermal noise which is constant over the bandwidth can be seen or plotted visually in cadence virtuoso and can we measure the MOSFET's thermal noise by this manner .. If so it can also be seen visually?

Thanks.

  • Resistors have thermal noise model am i right? Is there any thermal noise model for MOS also. I want to measure the thermal noise and Flicker noise of a MOS .. that is what i am asking.. Hope this is somewhat clear..
  • Resistors and MOS devices have thermal and flicker noise models - whether the flicker noise is available depends on whether the appropriate model parameters have been set. Generally speaking you get the thermal noise "for free" because this comes from the resistances in the devices and not much in the way of additional parameters are needed to control that.
