Voltage-Controlled Current Source
Linear voltage-controlled current source
The Voltage-Controlled Current Source block models a linear voltage-controlled current source, described with the following equation:
|Voltages presented at the + and – control ports|
To use the block, connect the + and – ports on the left side of the block (the control ports) to the control voltage source. The two ports on the right side of the block (the output ports) generate the output current. The arrow indicates the positive direction of the current flow.
To set the priority and initial target values for the block variables prior to simulation, use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector). For more information, see Set Priority and Initial Target for Block Variables.
- Transconductance K
Transconductance, or the change in output current divided by the change in input voltage that causes it. The default value is
The block has four electrical conserving ports. Connections + and – on the left side of the block are the control ports. The other two ports are the electrical terminals that provide the output current. The arrow indicates the positive direction of the current flow.
