What is significance of using parameter sweep and DC simulation in QUCS?

Simulation with Parameter Sweep. Simulation result using parameter sweep simulate the each resistor value at the same time instead of simulating it one by one. Its is efficient and users can compare the result at the same time.

What is a parameter sweep?

Parameter sweep runs a series of simulations, as a selected parameter in the circuit is varied for each simulation run. You select a specific parameter of a component to sweep in Simulation settings. Analysis types available for simulation include Transient, AC sweep and DC operating point.

Where can a parameter sweep be used?

simulations
Parameter sweeps are useful for finding the optimum value of a parameter, and for studying the sensitivity of the design performance to certain parameters or running a series of simulations with a set of varying parameters.

What is parametric sweep in Comsol?

Study / Parametric Sweeps Instead of manually changing these property values and re-solving each time, you can perform a parametric sweep with COMSOL Multiphysics®. A parametric sweep allows you to change the parameter values through a specified range.

How do you do a parameter sweep in Matlab?

Sweep MATLAB Variables with MATLAB Scripting

  1. Open sldrtex_inlined and the Scope block.
  2. In the base workspace, create a parameter object configured to store the parameter as a global variable.
  3. Replace the Transfer Fcn block parameter Denominator with the parameter object.

What is auxiliary sweep in Comsol?

The auxiliary sweep however is used when material property comes into question. It can be used to vary material property such as density, thermal conductivity, or any other material coefficient. In addition, this feature can help you determine a material property based on experiment results. Good luck. Cite.

What is a parameter sweep Matlab?

When you sweep one or more parameters, you change their values between simulation runs, and compare and analyze the output signal data from each run. You can sweep block parameter values or the values of workspace variables that you use to set the parameter values.

What is parameter sweep Comsol?

How do you do a parametric sweep in Matlab?

How do you create a frequency sweep in Matlab?

y = chirp( t , f0 , t1 , f1 ) generates samples of a linear swept-frequency cosine signal at the time instances defined in array t . The instantaneous frequency at time 0 is f0 and the instantaneous frequency at time t1 is f1 . y = chirp( t , f0 , t1 , f1 , method ) specifies an alternative sweep method option.

What is material sweep in Comsol?

A Material Sweep study solves your model with materials that you specify and provides you with comparative results of how those materials affect your model. This is done by adding a material Switch node, specifying the materials to switch between, and then adding a material sweep to your study.

How to calculate parameter sweep in qucsstudio Part 2?

Additionally working with a „Parameter Sweep“ you have a huge stock of data and results. You can calculate the relationship between the input voltage and the distortions over the frequency, the 1 dB compression point, the IP3 point, the spectrum of generated harmonics…..and so on…and so on….

Where does the supply voltage come from in qucsstudio?

The supply voltage ist named „Vdd“ as preparation for a Parameter Sweep The Input RF Signal comes from the voltage source V3. Its frequency is f =1.9 GHz and the amplitude is also given as a variable named „u_RF“ (for another Parameter Sweep).

How to find simulation gap in AC sweep?

An „ACSweep“ ignores every nonlinearity and shows only the Transfer Functions for sine wave input signals with constant amplitude. So you find a „Simulation gap“ if you want an AC sweep and afterwards present the „nonlinearities over frequency“ for different amplitudes or frequencies of the input signals.

How to close a simulation gap in qucsstudio?

So you find a „Simulation gap“ if you want an AC sweep and afterwards present the „nonlinearities over frequency“ for different amplitudes or frequencies of the input signals. This gap is now closed by the „Harmonic Balance Simulation“ which is a free part of qucsstudio.
