How does a voltage controlled resistor work?
A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.
How do you rotate a resistor in PSpice?
Just select the part and drag it where you want it. To rotate parts so that they will fit in you circuit nicely, click on the part and press “Ctrl+R” (or Edit “Rotate”). To flip them, press “Ctrl+F” (or Edit “Flip”). If you have any parts left over, just select them and press “Delete”.
What is print step in PSpice?
The ratio of final time and print step determines how many calculations PSpice must make to plot a wave forms. PSpice always defaults the start time to zero seconds and going until it reaches the user defined final time.
Which device acts like a current controlled resistor?
Transistor is a device which can act as both as a resistor as well as diode.
How is gain calculated in PSpice?
In order to determine the differential gain (in theory or in PSpice), you must put in a pure differential AC input (Vin1 = -Vin2). Then the differential gain is computed as Vout/(Vin1-Vin2). In order to determine the common-mode gain, you must put in a pure common-mode input (Vin1 = Vin2).
How do I change the direction of a resistor in Ltspice?
If you want to rotate the resistor before placing, press “ctrl+R” or click the rotate button. Left click where you want to place the resistor.
What are the advantages of PSpice?
PSpice lets you simulate and analyze your analog and mixed-signal circuits within OrCAD. PSpice calculates complex node voltages and branch currents at each frequency across your design, allowing you to place probes and generate waveform plots for further analysis.
