I have created layout a for transmission line using commercial IC technology PDK and performed sp simulation in ADS.Is it possible to get loss parameters(RLGC) of the transmission line in ADS so that I can model the loss mechanisms.
There are equations that can give you the RLGC parameters from the 2-port s-parameters of a 2-port network, assuming that network is a piece of transmission line. A good paper that is openly available on the internet which summarizes these equations is Extraction of Transmission Line Parameters and Effect of Conductive Substrates on their…
I created a Matlab script that creates a histogram variable "Counts" depending on which path and measurement I want to analyze from corresponding MonteCarlo datasets. "Counts" contains the bin values (specified by the script and stored in either the default "__HistIndep" or whatever the user specifies) and number of samples from the MonteCarlo…(Show moreShow less)
Hi, Have imported a simple flex ribbon cable Allegro layout into SiPro which worked fine. Setup all of the ports and finished the simulation which completed and converged without any warnings or errors. Went to the S-Parameters plotter under "Results", then went to the "Mixed Mode" tab and started selecting individual lines to pair together…(Show moreShow less)
Hi, i've got strange bug during optimization in ADS. I've make schematic based on few SnP files and AMI model of FPGA Tx and Rx to perform SI analysis and optimize transciever parameters. So i've specify Tx and Rx AMI-parameters by variables, make them optimizable with discrete step, and run optimizer. When i check results i saw that otimizer…(Show moreShow less)
I am simulating a Power amplifier design and my input is an envelope modulated signal with a sampling frequency 92.16 MHz. while using envelope simulation the "TIme Step too small" error is coming. And it is taking too much time to simulation if i reduce the sampling frequency to 92.16 * 10^4 Hz. How i can solve this problem. Is there any…(Show moreShow less)
There are a number of steps one can take to address Envelope convergence issues. First of all the "time step too small" error is not necessarily literally true. Sometimes convergence can be attained by either increasing or decreasing the time step, typically in multiples of 2. The time step is inversely proportional to the simulation bandwidth,…
Hello, I need to know how to fill the ideal frequency multiplier data based on the datasheet. I will be grateful if you could let me know for this specific component. (My mixer is RMK-5-571+ mini-circuit)
I have the gerbers for a PCB antenna, which I have imported into a Genesys layout. Changing the length of the antenna element changes the antenna's resonant frequency. How do I get Genesys to tell me how long it has to be to achieve a certain resonant frequency? I don't have a schematic for this design, since I just imported the gerbers. Is it…(Show moreShow less)
Hi, all I have a problem that how to extract the circuits from microstrip in Fig1? I have measured the S parametre of the microstrip as a 2-port network and then how to fit the measured S_parametre by extracted circuits in ADS?
Hi, you have to use the optimizer to fitt the lumped model parameters. Error funtion to minimize is the ddetla between measured and simulation results. For this purpose it's required to load the measured data at simulation runtime via a DAC component. Straight forward. Toby
