How do you simulate sound in PSpice?

To calculate the equivalent noise, PSpice A/D then divides the total output noise by the gain from the input source to the output net. This results in the amount of noise which, if injected at the input source into a noiseless circuit, would produce the total noise originally calculated for the output net.

How do you make a subcircuit in PSpice?

The name of the subcircuit is created from the schematic name….

  1. Choose Tools – Create Netlist.
  2. Click on the PSpice tab.
  3. Check the Create Subcircuit Format Netlist check box.
  4. Change the path of the library file to your training directory so that you can find it later.
  5. Click OK.

How do you use AC sweep in PSpice?

To access them, go to PSpice in the menu, Markers, Advanced, Select dB Magnitude of Voltage, and place the marker on the output now. You can add an advance marker to measure the phase of voltage, too. Now you have successfully performed an AC sweep analysis and displayed a Bode plot with PSpice.

What is noise analysis?

Noise analysis is run in conjunction with an AC analysis, and calculates the output noise and equivalent input noise in a circuit. The output noise, at a specified output node, is the root mean square sum of the noise generated by all the resistors and semiconductors in the circuit.

How do I add a library to PSpice?

From Pspice Schematics menu: Choose Analysis -> Library and Include Files Click on Browse, find cmos. lib, and click on Open Click on Add Library* Click on OK.

How do you create a netlist in PSpice?

Lab 5-1: Creating a Text Netlist

  1. From within OrCAD Capture or PSpice A/D choose File – New – Text File.
  2. Type in the netlist for the schematic below.
  3. After entering the netlist description add a .
  4. Add a library call for nom.
  5. Add an AC sweep analysis specification.
  6. End the file with an .
  7. Save the file as CLIP_NL.

What is AC analysis in PSpice?

For an AC sweep analysis, PSpice A/D calculates the small-signal response of the circuit (linearized around the bias point) when sweeping one or more sources over a range of frequencies. Outputs include voltages and currents with the magnitude and phase, which you can use to obtain Bode plots.

What is DC sweep analysis?

DC Sweep Analysis is used to calculate a circuits’ bias point over a range of values. This procedure allows you to simulate a circuit many times, sweeping the DC values within a predetermined range. You can control the source values by choosing the start and stop values and the increment for the DC range.

How does LTspice perform noise analysis?

LTspice calculates the total noise within a frequency band by first running the simulation over the frequency band of interest. For example, use 500 Hz to 1500 Hz. Then, plot the output noise. While holding down the CTRL key, left click on the V(onoise) label at the top of the plot.

What are exceptions in noise analysis?

The most interesting part of NOISE analysis is the part labeled ‘Exception. ‘ Basically, this part is meant to encourage collaboration between the members of the team. It looks at what is already happening among the other elements of the analysis, even if only by a bit .
