Abstract: A virtual ground memory array (VGA) is formed by a storage layer over a substrate with a conductive layer over the storage layer. The conductive layer is opened according to a patterned photoresist layer. The openings are implanted to form source/drain lines in the substrate, then filled with a layer of dielectric material. Chemical mechanical polishing (CMP) is then performed until the top of the conductive layer is exposed. This leaves dielectric spacers over the source/drain lines and conductive material between the dielectric spacers. Word lines are then formed over the conductive material and the dielectric spacers. As an alternative, instead of using a conductive layer, a sacrificial layer is used that is removed after the CMP step. After removing the sacrificial portions, the word lines are formed. In both cases, dielectric spacers reduce gate/drain capacitance and the distance from substrate to gate is held constant across the channel.

Abstract: A clamping circuit of a DC/DC regulator includes a reference current generator to generate a reference current. The reference current can be based upon a specified maximum voltage across a bootstrap capacitor of the DC/DC regulator. The clamping circuit also includes a current generator that generates a current based on the voltage across the bootstrap capacitor. The current generated by the current generator is compared to the generated reference current. Based on the comparison, the voltage across the bootstrap capacitor is regulated. By regulating the voltage across the bootstrap capacitor based on current, rather than based directly on the voltage across the capacitor, the design of the clamping circuit is simplified compared to voltage-based implementations.

In a one dimensional migration barrier, the migration barrier extends laterally through the source/drain regions while, in a two dimensional barrier, the barrier terminates laterally at boundaries defined by the gate module.

Abstract: Method and system for tuning a tunable antenna uses a comparison between a signal response at two different tuning frequencies to determine how or if the tuning needs to be further adjusted. With the approach, the method and system arrive at a frequency shift that is centered about the desired antenna frequency, which point there is no net change in the signal response. In a further aspect, a frequency to which a tuned antenna is tuned is shifted to verify whether the antenna is still in tune. Modifications to minimize disturbance of the output received signal that would otherwise be caused by the frequency shifting are contemplated.
