Abstract: The present invention provides a device, a method of making the device, and a system incorporating the same. In one embodiment, the device includes a substrate that has first and second opposing surfaces and first and second thicknesses, wherein the second thickness is less than the first thickness, and the first surface is substantially planar. The device further includes a conductive trace having an input end and an output end and located over the first surface of the substrate, wherein at least one of the input end or output end is aligned with the second substrate thickness.

Abstract: In magnetic bubble memories both linear and switched drive circuits are presently in use. The linear circuit can employ a capacitor to achieve resonance and may operate at a relatively high efficiency. However, when a linear coil drive circuit, which had been designed to operate at resonance, is operated just off resonance a substantial loss of power efficiency is observed. A switched coil drive circuit is described herein which achieves high operating power efficiency by using a capacitor in parallel with the bubble coil.
