## Modelling of Switched reluctance motor phase

Hello together, i want to know how it is possible to modelling the phase of an switched reluctance motor for circuit simulation. I have to develop a cicuit which is able to controll the dc link voltage but i have no idea how to simulate the coils of the srm. How can i put an equivalent model of the coils in my simulation. (...)

## transformer matching circuit equivalent in virtuoso

Dear all, I need some help. I am designing a transformer matching circuit on virtuoso. As per my understanding, we can estimate the value of self inductances, L1 and L2 (first photo) using the transformer electrical model equivalent circuit (second photo). 137395 137396 How can I create th

## planar inductor or capacitor

Dear sir i am tying to model below circuit(tank) into its distributed(DC) equivalent circuit..... Thanks Look at this Application Note of Volker Muhlhaus because you do something wrong.

## Is there any SMA Connector Model available ?

Is there any equivalent circuit or S-parameters of SMA Connector around 1GHz ?

## Microstrip Patch Antenna Ansoft Designer

An equivalent-circuit model for the patch antenna can be found in Balanis' "Antenna Theory: Analysis and Design" textbook, and probably elsewhere on the internet. Basically, you want to create a lossy, half-wavelength resonator, the characteristic impedance of which differs significantly from your system impedance.

## Signal integrity using tool hyperlynx IBIS model

Can i use 50 ohm pull down termination as receiver and simulate the transmission line. Yes, if the receiver or your external circuit involves a 50 ohms termination. For a high impedance receiver, you can try to estimate an equivalent circuit from datasheet values. IBIS data also describes nonlinear input behavior like clamping diode

## cross coupled lc oscillator

Varactors can be trouble in term of model.Using equivalent circuit instead of its model may help.

## Differing Circuit Models for Cavity Resonators

I've been trying to reconcile two circuit models of cavity resonators. Background: Its commonly known in order to measure a cavity resonator, one has to "load" the resonator with however you wish to excite it (probe, loop, etc.). Parameters such as the length of your probe or size of your loop will affect the measured Q and f0. But thes

## Ring oscillator: small signal model

I believe that the equivalent circuit is somehow counter-intuitive. It implements a trick and rearranges the circuit to cut the stages at currentless points. The current generated by both Cgd instances is split into two terms each, utilizing Vgd = Vgs - Vds. As far as I see, there's nothing left, the equivalent (...)

## Extracting broad band RLC model from S-parameters for a DGS band-stop filter.

Hi, The S-parameters for a DGS band-stop filter by EM simulation in shown in the figure below. 122475 The band-stop model can be easily extracted by parallel RLCs. The figure attached below shows the equivalent RLC circuit model with its frequency response. 122476122477[/AT

## which resistor, capacitor, should be used in RF design

First simulate your design with ideal capacitors and inductors. Then replace them with their equivalent model or measured data and tune the circuit again to get the desired response.

## TSC4429 IC in flyback rectifier modeling in matlab simulink

I want to model the following attachment by matlab simulink. but I don't know that what is "TSC4429" IC! it is "gate driver" of "Q transistor". can you give me datasheet or equivalent circuit of "TSC4429" IC? how model it in matlab simulink? 116531

## Reproducing a circuit with non linear components from netlist

how spice replaces the transistor with its equivalent model in the sparse matrix while performing MNA It should be quite obvious from descriptions of circuit simulator operation what SPICE or any SPICE based simulator does. It performs an initial transient solution to determine the operation point, then calculate the node impedan

## Need help with a radio transmitter 27 MHz - AM

Some Spice simulators have problems to start an oscillation when using a crystal model, or the equivalent circuit of a crystal. Replace the entire equivalent crystal circuit with a simple shunt LC circuit (1uH and 33pF, and keep C9 in place) and you will get the 27MHz oscillation, just to (...)

## Using "PSPICE" software, Can we generate equivalent CKT and Obtain desired Parameter

I downloaded and installed the Student Version Electronics Lab "PSPICE" software. I have the following doubts regarding on the "PSPICE" software (1) From " PSPICE" software, can we import our normal electronic circuit and convert it into equivalent circuit for small signal analysis. (2) If we import our small signal (...)

## Exporting equivalent circuit from HFSS for apertured frequency selective surface

hi. can u help me in extracting equivalent circuit From HFSS

## How to extract parametres of pi and t circuit.

It's not generally possible to translate s-parameters to an equivalent circuit. ADS has "linear data file components", e.g. S2P to represent s-parameter data. Review CCSIM manual.

## Noise transfer function

Hi, I have attached BSIM equivalent model of MOS. I want to know the (transresistance) transfer function from drain channel noise source to the internal vgs of the MOSFET (Not between external G and S but internal vgs excluding Rg and Rs drop) in a particular circuit. I know how to use pss+pnoise+noise separation but I can only choose (...)

## Question regarding HFSS's equivalent circuit export

This is probably a really dumb question, but I've scoured every tutorial I could find and just couldn't find the answer to this. I am trying to export an RLGC lumped model of some stuff I made in HFSS, and then dump this file into the mtline instance in Cadence Virtuoso. The simulator I'm using is spectre. It seems like everything I've tried

## Help needed to solve these complex set of equations!!!

Hi, I am trying to model my circuit response. The frequency response and its equivalent circuit model is shown in the figures below. 106990 106991 At the S21 dip (transmission zero - stop-band), the susceptance of the equivalent circuit = 0. Hence, Ys cot (...)
