What is AC sweep and DC sweep?

While a DC sweep is designed to sweep through different voltage values of a DC source, an AC sweep is designed to sweep through different frequencies at a constant amplitude. This allows you to examine how the output voltage/current throughout the circuit respond to different driving frequencies.

What is V sweep in AC?

AC sweep simulation is used when you want to calculate the small-signal response of a circuit. This method will first use operating point analysis to gather linear, small-signal models for all nonlinear components. The snapshot of this circuit is then analyzed based on a defined frequency range.

What is AC analysis and DC analysis?

AC analysis gives the voltage or current versus frequency in a linearized version of the circuit. DC analysis gives DC voltage or current, usually versus a stepped voltage or current. In principle, each analysis should give results that agree with the others, if looked at correctly.

What is a 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.

What is sweep voltage?

[′swēp ‚vōl·tij] (electronics) Periodically varying voltage applied to the deflection plates of a cathode-ray tube to give a beam displacement that is a function of time, frequency, or other data base.

What is sweep mode?

In sweep mode, the instrument outputs a single sweep when a trigger signal is received. After one sweep from the start frequency to the stop frequency, the instrument waits for the next trigger while outputting the start frequency.

What is the purpose of DC analysis?

How do you do a DC analysis?

DC analysis of a common-emitter amplifier circuit begins with determining the dc bias values and then removing coupling and bypass capacitors, the load resistor, and the signal source to produce a dc equivalent circuit by applying Thevenin’s theorem and Kirchoff’s voltage law.

What is Sweep time?

The sweep time is the time that the analog spectrum analyzer needs to sweep through the frequency range from the starting frequency FStart to the stopping frequency FStop.

How is an AC sweep different from a DC Sweep?

While a DC sweep is designed to sweep through different voltage values of a DC source, an AC sweep is designed to sweep through different frequencies at a constant amplitude. This allows you to examine how the output voltage/current throughout the circuit respond to different driving frequencies.

How to setup an AC sweep simulation profile?

The AC sweep simulation analysis is configured through the Simulation Setting dialog box in much the same way as the DC bias analysis and the DC sweep analysis introduced in Lessons 2 and 3. When you setup the AC sweep profile, you can specify the analysis type as being either linear, octave, or decade.

How does a DC Sweep analysis work in EMA?

What is DC Sweep Analysis? DC Sweep analysis calculates the steady-state voltages and currents when sweeping a source, model parameter, global parameter, or temperature over a range of values. You can view the results of a DC sweep analysis in either a text output file or in the graphical display of the Probe window. DC Sweep Settings and Options

What’s the default value for a DC Sweep?

The most common DC sources to use for a DC Sweep analysis are the VDC (voltage source) and the IDC (current source). Both of these symbols have a default value of zero, which is displayed next to the placed symbol.
