20110024835 | HIGH FREQUENCY FIELD-EFFECT TRANSISTOR - The invention relates to a field-effect transistor having a higher efficiency than the known field-effect transistors, in particular at higher operating frequencies. This is achieved by electrically connecting sources of a plurality of main current paths by means of a strap line (SL) being inductively coupled to a gate line (Gtl) and/or a drain line (Drnl) for forming an additional RF-return current path parallel to the RF-return current path in a semiconductor body (SB).

20110128111 | PLANAR, MONOLITHICALLY INTEGRATED COIL - The present invention provides a means to integrate planar coils on silicon, while providing a high inductance. This high inductance is achieved through a special back- and front sided shielding of a material. In many applications, high-value inductors are a necessity. In particular, this holds for applications in power management. In these applications, the inductors are at least 5 of the order of 1 μH, and must have an equivalent series resistance of less than 0.1 Ω. For this reason, those inductors are always bulky components, of a typical size of 2×2×1 mm 3, which make a fully integrated solution impossible. On the other hand, integrated inductors, which can monolithically be integrated, do exist. However, these inductors suffer either from low inductance values, or 10 very-high DC resistance values. | 06-02-2011 |
20110148558 | INDUCTOR - An inductor includes a conductive track forming at least three inductor turns. The conductive track has a plurality of track sections. The inductor also includes at least two groups of crossing points, each crossing point comprising a location at which the conductive track crosses over itself. The crossing points of each group collectively reverse the order of at least some of the track sections in the inductor, such that inner track sections of the conductive track cross over to become respective outer track sections, and such that outer track sections of the conductive track cross over to become respective inner track sections. | 06-23-2011 |
20110151803 | Fringe Capacitor Circuit - Capacitive circuits are implemented with desirable quality factors in various implementations. According to an example embodiment, a fringe capacitor includes two capacitive circuits (e.g., plates), respectively having a plurality of capacitive fingers extending from an end structure, and respectively having a connecting pin that is adjacent the connecting pin of the other capacitive circuit, on a common side fringe capacitor. The capacitive fingers are arranged in stacked layers, with vias connecting the fingers in different layers back to the connecting pins. | 06-23-2011 |
20120044034 | SYMMETRICAL INDUCTOR - A symmetrical inductor having at least one inductor turn. Each inductor turn has a plurality of separate conductive paths having substantially equal inductance. The inductor also comprises a plurality of crossing points. At each crossing point, some of the conductive paths within a given inductor turn cross over each other to change the order in which they appear within the inductor turn. | 02-23-2012 |
