ABSTRACT:
A method of making an inductor and the inductor. The inductor comprises a plurality of serially connected transistors at least partially formed in a substrate, preferably a silicon on insulator substrate, and comprises a gate common to the plurality of transistors. The plurality of transistors, transistor contacts, and electrical interconnects form the coil of the inductor and the gate common to the plurality of transistors forms the core of the inductor. Two inductors of the invention are magnetically coupled to form a transformer of the invention. A control transistor is serially connected to the primary inductor of the transformer. The control transistor is gated by a periodic output signal of a ring oscillator. An actuation and a deactuation of the control transistor allows the current in the primary coil to vary creating a changing magnetic flux in the primary and secondary cores and inducing a fluctuating current in the secondary coil.
