A Voltage Controlled Current Source (VCCS), where the current is controlled by the voltage across the VCCS element itself, acts just like a resistor. This can be created using a behavioral expression referencing the current source's own voltage drop.
This example is from the Dependent (Controlled) Sources chapter of Ultimate Electronics Book. It shows a DC Sweep simulation showing that a self-connected VCCS acts just like a resistor.
This takes advantage of CircuitLab's support for Behavioral Sources, where you can define a voltage or current source's value with a simple mathematical expression.
In this case, a current source element I1 is defined as having a current that is
0.01 * V(), i.e. its own voltage drop
V() multiplied by some gain. The result acts like a resistor.
