An fully integrated DC-to-DC switching converter having an inductor, where the inductor has magnetic material that may be amorphous CoZrTa, CoFeHfO, CoAlO, FeSiO, CoFeAlO, CoNbTa, CoZr, and other amorphous cobalt alloys. The magnetic material allows for a relatively high switching frequency. In one embodiment, the inductor has two sub-structures, where each of the two sub-structures are parallel to each other and each includes a conductor having upper and lower portions. The conductors of the two sub-structures are electrically connected to each other, and the upper and lower portions are arranged so that magnetic flux from one of the sub-structures couples with the magnetic flux from the other sub-structure so as to provide a relatively high inductance with small form factor. In another embodiment, the inductor is a simple conductor surrounded by high-frequency magnetic material. In both structures, oxide insulates the conductors from the magnetic material.

An extraction system detects a voltage stored in a capacitor and then extracts energy from the capacitor when the voltage falls below a predetermined value. The capacitor may be an ultracapacitor formed in silicon or another semiconductor material, and the predetermined value may equal or be based on a minimum operating voltage of a load driven by the ultracapacitor. Once the energy is extracted, the system converts the energy into a voltage sufficient to continue driving the load. Energy extraction may be performed by a variety of circuits including a linear regulator, a switched capacitor voltage converter, an adiabatic amplifier, and a DC-to-DC boost converter. The system may further include a monitoring circuit which detects dynamic changes in the converted ultracapacitor voltage over to maintain the operating voltage of the load.

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

Embodiments of the present invention relate to independently switched inductors in a voltage converter. Each voltage transforming inductor of a voltage converter may be deignated a switch or bridge at each opposing terminal. The function of these switches is to periodically reverse the polarity of voltage across the inductors. By configuring independently switched inductors in series, the frustration of voltage tolerance limitations of the switches is mitigated.
