ABSTRACT:
An inductor is connected in parallel with a capacitor. A first and a second current source provide current to the inductor in opposite directions. Rapid current switching in the inductor is achieved by allowing the inductor and capacitor to resonate in a time period between the application of current from the first and second current source.
