frequency range: i thought to specify the range from zero till the frequency of the oscillation i got fro the transient plot and f=1/T. The final ADEL shown bellow. When i tried to run the PSS first ,it gave me an error shown in the end. Why it gave me an error? my VCO is os...
it is necessary to set the pss beat frequency to 240MHz. The beat frequency of pss and pnoise will automatically be the same value. In order to check the phase noise of OUTB (480MHz), I stopped the circuit operating at 240MHz
However, when I do the simulation, the PSS is ok but for PNOISE, there is an error: "error (sfe-51): name conflict: value `vco_vout' of type `scalar string' encountered. expected value is of type `scalar instance'." According to the"VCO spectreRF workshop",there are two Idc compo...
the spectre log file summaries the convergence failures <fig.2>, even at the end, "conv norm" approaches to smaller than 1. I don't really get the mechanism here. could you help me to explain this point? Finally, simulation goes through to PSP to get S parameter responses, however, so...
Hi, 1) Why do I get different results in the PSS and Transient Analysis when using the NPORT of the EMX Simulation. For example, when I use the rational interpolation
I am using Virtuoso version ICADVM20.1-64b.500.15 for simulation. Below is my test bench, in which the switch is driven by a 8GHz 25% duty cycle clock. The closed switch resistance is 0.1Ohm, while the open resistance is 1T Ohm. And the RC time-constant is 15GHz, which is higher ...
Hello, I am using Virtuoso 6.1.7, spectre version 18.10.169. I am simulating a 32kHz relaxation oscillator with pss/pnoise to get phase noise/jitter. I want
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
