Nonlinear Dependent Source
 National Instruments Corporation 1-21 Multisim Component Reference Guide
1.23.2 Exponential Current Source
This component is the same as the Exponential Voltage Source, except that the output is
measured in current.
1.24 Nonlinear Dependent Source
Use this source for analog behavioral modeling. This generic source allows you to create a
sophisticated behavioral model by entering a mathematical expression.
This source uses analog behavioral modeling through mathematical expressions.
The output voltage or current can be a function of up to four voltages and two currents.
Voltages and currents are referenced by connecting the input pins of this device to schematic
nodes.
For a more flexible solution, see “ABM Sources” on page 1-49.
 To change the nonlinear dependent source’s value:
1. Double-click on the placed component and click the
Valu e tab.
2. Complete the
Source Expression.
Note If you set the dependent variable to “V”, the output is in voltage; if you set it to “I”, the
output is in current.
1.25 Controlled One-Shot
This oscillator takes an AC or DC input voltage, which it uses as the independent variable in
the piecewise linear curve described by the (control, pulse width) pairs. From the curve, a
pulse width value is determined, and the oscillator outputs a pulse of that width. You can
