Notice the new symbol appearing in the property dialog of the part. Click the button labeled "Edit Model..." on the right side of the dialog. A new dialog open ups with the title: "'''Edit Subcircuit Text'''" as shown in the above figure. Here you see the Netlist code for your model, which is in fact the Netlist representation of your original voltage doubler circuit minus the voltage source. You can edit this Netlist model at any time if you like. Close both dialogs and return to the [[Schematic Editor]].
Now, insert a new sinusoidal voltage source with an amplitude of 5V and a frequency of 1MHz identical to the previous section of the lesson. Connect it to the "IN" port of your device. Connect the "GND" pin of your device to the new circuit's ground. At the "OUT" pin of the device, place a large 1M resistor as a sort of "Open" load. Your new circuit should like the figure below:
