    摘要: A TE0&ggr;&dgr; mode dielectric resonator (12) includes a cylindrical dielectric disk (32, 32′, 32″) having top and bottom ends (20, 22) spaced apart by a closed curve wall (24). The dielectric disk has an effective dielectric constant greater than 40. An axially aligned hole (36) is formed through the disk (32) between the top and bottom ends (20, 22). A conductive wall (34, 34″) is formed at or slightly beyond the wall (24) but does not cover the top and bottom ends (20, 22). The hole (36) has a preferred diameter between 0.21 and 0.4 times the diameter of the disk (32, 32′, 32″). The disk may be configured as a heterogeneous composite of dissimilar materials which exhibit increasing dielectric constant at increasing radial distance and increasing Q at decreasing radial distance.

    摘要: A static RAM memory cell (30) uses cross-coupled enhancement mode, N-channel MOS drive transistors (36) to form a bistable flip-flop. A load circuit (34) couples between I/O ports (40) of the drive transistors (36) and Vcc. For each drive transistor (36), the load circuit includes a depletion mode, N-channel MOS load transistor (54) and a forward biased tunnel diode (32). The drain and gate of the load transistor (54) couple across the anode and cathode of the tunnel diode (32) so that the forward voltage (Vf) of the tunnel diode (32) controls the Vgs transfer curve (56) of the load transistor. The tunnel diode (32) may be formed at a junction between a mono-crystalline silicon layer (88) at a region (98, 100) which also serves as a source or drain of a transistor (36, 54) and a poly-crystalline silicon layer (106). The poly-crystalline silicon layer (106) also serves as a non-metallic, conductive interconnection (55) to save space.

    摘要: A monolithic inductor (20, 20′) is formed over a silicon or other substrate (22). The inductor (20, 20′) includes at least one coil (62, 78) arranged so that its axis (58) is parallel to the substrate (22). Other inductive features, such as other coils (64, 70, 72) or planar spirals (74, 76) are arranged in series with the coil (62, 78) to guide magnetic flux lines away from the substrate (22). In one embodiment, a common thin film coil core (60) made from a magnetic material is provided for two coils (62, 64). The coil core (60) provides a continuous magnetic material flux path through the two coils (62, 64). In another embodiment, an axis (58) of the coil (78) is located between the plane in which two spirals (74, 76) are located and the substrate (22) to guide magnetic flux lines (82) away from the substrate (22).
