## Why results from EM simulaiton different from schematic simulation?

Hi all, I am designing an amplifier. I finished the schematic and working on EM simulation right now. But they are actually not the same. What would be reasons? Thanks. When you start to follow a proper design flow. You will understand why. 1. Design your matching network with a ideal lumped component

## Transformer matching network design

Dear all, I am a beginner. I need some opinion/help. Here is my situation. I am designing a transformer matching network (TMN) for a PA. I do not have ADS PDK but working in CADENCE PDK. My question is do I have to design layout in CADENCE then export gds file to E.M software such as HFSS/ADS momentum for electromagnetic simulation and

## Offsetting opamp output

I have a DC voltage derived from a sensing resistor divider network which is in the range of 1.5V to 2.5Volts. How can I amplify and offset this voltage to the range of 0-5V for MCU ADC? I have +12V available. Thanks

## Phased Array Simulation

Hello Everyone !!! I'm simulating a linear 4 elements patch array on ansoft designer v2.2 at a single frequency I've placed, in the planarEM, the four patches with separate ports. Now I need to view the antenna beam moving with the phase difference of the port excitation. If i simulate the network and, after, i visualize the far-field,

## How to confirm that your impedance matching is a good matching with ADS

The simplest way I can imagine is to plot the smith chart. So make a port, your matching network, and your load, then simulate at the frequency of interest using the S parameter simulation. Plot the smith chart and see if the line crosses the center of the chart right at the frequency you care about. Moreover, ADS has a handy impedance matching uti

## How to simulate the Doppler shift in cellular (relaying network) system?

Is there a Matlab code (simulation) to insert the effect of the Doppler shift in frequency, due to the mobility of the user in a relaying communication system? if anyone knows how to do it, can you please provide me with the code?? I'm trying to evaluate the system performance in the relaying network, i did it without the effect of the mobility

## RSRP and RSRQ cell selection method heterogenous network matlab simulation

Please suggest me a matlab code to find the best cell in a cell network with 19 hexagonal cells, each having 3 sectors and 4 small cell(pico cell) base stations are in one sector. The cell selection methods are Reference Signal Received Power(RSRP) and Reference Signal Received Quality(RSRQ).

## MNA-MAT : An easy-to-use MATLAB tool for SPICE netlist simulation

MNA-MAT, a MATLAB based analog circuit simulation tool, uses Modified Nodal Analysis to reduce a SPICE netlist to a system of equations which yield voltage at and current through specific points in the network. Monte Carlo analysis adds further functionality by evaluating possible uncertainties in real-world working conditions. The tool,

## Three winding transformer with symmetrical resonant tanks for isolated dc-dc converter

May be your "standard equations" are wrong. It's a simple AC network and can be well calculated. If you want others to check it, you should post the complete calculation, including a source/derivation of the standard equations.

## Simulation terminated by process (manet_imep) at module (top.Campus Network.mobile_no

In OPNET simulation tool while running simulation i got this error. simulation terminated by process (manet_imep) at module (top.Campus network.mobile_node_3.ip), T (11.236) , EV (260) Terminating simulation in IMEP Please help me if anybody knows answer.

## difference in theoritical and simulation results

i have an antenna whose Zin i have calculated and then use a lumped network(L- shaped network using inductor and capacitor) to match that to a 50 ohm line at 2.4 GHz.now when i am simulating this on hfss i am getting some other resonant frequency so on slightly changing the lumped elements value it is getting tuned to 2.2 GHz but not on 2.4, also e

## importing multiple (touchston)S1P in ads?

I got many S1P file from network analyzer.now i want to import these file into ads . i already import a single file but i need to import all the file at a time so that i can compare the result so pleas help in this issue.

Without looking at your design, I'd have to say that it's expected. Commercial Yagi antennas typically have some kind of matching network (Gamma, Delta, etc.) to tune the antenna impedance to near 50/75 ohms.

## CST Simulation not matching network analyzer

I created a dipole antenna in CST and built it by hand using componants in my lab. The problem is that when I use the network analyzer to measure the impedance and VSWR, the results are not the same as the simulation. I can create a matching circuit using ADS or change the measurements of the length/width of the dipole, but I feel that this sho

## Monte Carlo simulation Error

Hi To me it doesnt look that you are doing a monte carlo simulation: you can see this in the toolbar "Single Run, Sweeps and Corners". This should be Monte Carlo Analysis Then on the error you are getting, it seems you are having a network/server error. Are you running the job locally?

I am designing an electrically small antenna loaded by negative capacitor realized by negative impedance converter. In HFSS, the antenna is treated as a two-port network, one port (Port1) for excitation, and the other (Port2) for negative capacitor placement. After HFSS simulation, the S2P file was extracted and imported into ADS. In ADS, t

## HSPICE Transient Iterations

Hello all, I have a large RC network that I am simulating in HSPICE (on Linux). The voltage sources are all DC and the current sources are random PWL signals. I am trying to figure out the number of system solves that HSPICE is performing to finish the simulation. In the output generated on the terminal, there are two entires: "tot. iter" and "c

## Suggestion: Simulation tool for WSN (time synchronization protocol)

Please suggest me some simulation tool to simulate time synchronization protocol for wireless sensor network.The other option for me is to work on hardware for that i have to understand tiny OS properly if anyone knows about tiny OS plz tell me from where to start..Hope i will get some solution from here..have a nice day :)

## cellular network simulation with MATLAB

Hi I need to simulate a cellular network in a 3G environment, consisting of 18 BSs that are located in center of cells. The total area is 5*5 km. I did'nt use MATLAB before. How can I create this in MATLAB? thanks
