I see a series stack of caps and MOS gates that has no DC path to ground in several spots (unless your MOSFET model has gate tunneling leakage, which is not that likely). Now I have no idea about ADS harmonic balance simulation but you might check whether it's using a good DC (OP) solution, or has tried to make its own and perhaps ignores the set
Hi everyone, I am trying to do rectenna at 1.9 Ghz with ADS, in rectifier part, i am taking "No convergence" error which is attached in figure 1, and my circuit also added in figure 2. Here is my questions; 1. What is this convergence error in ADS? What does it mean? 2. How can i fix this error? ps. I (...)
Did you try to change some time related parameters of the Simulation Options panel for transient analysis ? There you can select simulation optimized either to better convergence or better accuracy, or even manually change to another value higher than default.
Something is not converging but information you gave just tells this nothing more. So I can't pin down what exactly is problematic. A very easy way out of DC convergence issues, if you are using an unknown model, is assigning initial conditions for your circuit. It's probable that the model you are using has open circuits at initial step so those
Sometimes it helps to install high ohm resistors across troublesome nodes, or from a node to ground, etc. The high-ohm resistors permit a little current flow to exist, instead of no current flow. I believe the simulator has a more drastic decision to turn On a component that is completely Off, compared to when that component is already On a little
Hello dear guys and dear ladies; I am getting convergence error whil using FDTD method in FEKO. When I searched in the internet I reached very theoratical explanations and I am not numerical mathematic expert, just using FEKO. Can you explain me what is convergence in FDTD method ? Why may I be getting this error ? What (...)
Not sure if this will solve your problem, but I have fixed errors of convergence by using models for non-ideal components, including the simplest, like resistors, capacitors, etc...
i am trying to simulate an OSC including Extended Gaussian Disorder Model (or equivalently pasveer mobility model) in silvaco, but the solution doesn't converge (it had this warnings and errors: "error string found in output", "Newton algorithm did not converge in 5 iterations.","Bias step cut back more than 4 times. Cannot trap."). i tried to sol

hello, I have implemented the circuit shown in the image attached with this post. When i run the circuit it gives me and error i.e. "error -- convergence problem in transient bias point calculation". The simulation window shows these messages: **** 04/18/15 12:56:13 ****** PSpice Lite (October 2012) ****** ID# 10813 **** ** Profile: "S
Hello, I have tried to perform a transient noise analysis, but I received this error: error (SPECTRE-16192): No convergence achieved with the minimum time step specified. I have read the possible solutions, but I don't know how to change "cmin". Do you have any suggestion? Are there other things I can do?
I am using Agilent Advanced Design System 2011.10 for my circuit design. I am getting the "no convergence error" for my designed circuit to obtain HB2 Two tone swept power. I have used "OPTIONS" setting also. Even though I used "OPTIONS" settings also, am getting the " no convergence error". How to overcome this converg
I am simulating a circuit using devices designed using SILVACO ATLAS in Mixed Mode. Now, there is no convergence error while finding IV Characteristics of the designed device but when I'm using that particular device in a circuit, on simulation is giving me a message in the Command Bar which states Warning: Not A Numbers found in currents.
114100 It is the circuit I am designing on Proteus it is giving the following error "too many iterations without convergence" pleasee helppp
Hello, i hae a prblem in my smulation for antenna monopole when i run this prject this anayse is ok and run is about 2 hours and fnaly he dsplay me error in cnvergence what is the solution please
I have tried a simulation in HSPICE with a circuit composed of a ring oscillator( 601 CMOS converters),but failed. The library I used is 350nm craft level. The netlist is as follows: .LIB 'D:\HSPICE_sim\SMIC35_SPICE\TD-MM35-SP-2002v5T\ASCII\ASCII\hspice\Enhanced_MS035_v0p6.lib' tt .GLOBAL VSS VDD .PARAM AEMI=0 .PARAM FEMI=1000MEG

maybe you have some convergence problems sometimes are explained in the log .don't you. check your circuits connections carefully and your pss analysis parameters and the tones you've given before.
It looks to me that the simulator is having trouble finding a solution due to convergence problems. The reason for this can be many fold.. You can try standard convergence solving routines - - consult google good luck!
