=== What You Will Learn ===
[[RF.Spice A/D]] allows you to take a circuit and turn it into a user defined part. Almost any circuit can be turned into a part with just a few steps. The new device is stored in [[RF.Spice]]'s '''Parts Database'''. You can create multiple instances of your new device in any circuit. In this tutorial lesson, you will learn how to use B2.Spice's Device Editor. You will create a voltage multiplier circuit as shown below and then will turn it into a new database device. in this lesson, you will also learn how to set up a parametric sweep in [[RF.Spice A/D]].
