Abstract: An electronic circuit (300) includes first (302) and second (304) variable impedance devices coupled together. The fist (302) and second (304) variable impedance devices are designed such that each exhibits a transfer function which is substantially inverse with respect to the other about the operating point of the electronic circuit. This provides for an electronic circuit which exhibits verly low distortion characteristics. Circuits such as tunable filters, voltage-controlled oscillators (VCOs), receivers, etc. will benefit from using an electronic circuit (300) which exhibits such low distortion characteristics.

Abstract: A delay locked loop frequency synthesizer in several embodiments uses a primary delay line element (24) and one or more secondary delay elements (162 164, 270, 310). In one embodiment, a main delay line (24) is used to coarsely select a frequency output while a secondary delay element (162 164, 270, 310), either passive or active, is used to increase the resolution of the primary delay line (24). In the passive embodiment, a coarse and fine frequency selection is possible by selecting components from the output taps of the main delay line (24) as a driving signal for the passive secondary delay element (310) to provide the coarse adjustment and selecting an output from the secondary delay element (310) to provide the fine selection.

Abstract: A twisted-pair conductor line structure is formed on a substrate (22) having insulated conductive layers (10, 11). The conductive layers are used to form first, second, third, and fourth conductive planar segments (16). A first conductive link (17) joins the first and second planar conductive segments to provide a first signal path. Similarly, a second conductive link (17) joins the third and fourth planar conductive segments to provide a second signal path. The first and second conductive links are operatively arranged to form a twist (17) in the first and second signal paths, such that the resulting magnetic fields (57, 59) around the twisted conductive segments will be opposite to each other for cancelling each other out, in order to reduce the magnetic field radiation to the surrounding environment.

Abstract: High quality epitaxial layers of monocrystalline materials (66) can be grown overlying monocrystalline substrates (52) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. Devices(56) may be formed in the silicon wafer prior to growing the high quality epitaxial layers. Then, to achieve the formation of a compliant substrate, an accommodating buffer layer (65) is grown on silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer (62) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Compound devices (68) are then formed on the overlying monocrystalline layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials. Silicon devices and circuits (e.g., CMOS circuits) in the silicon wafer are wired (70) to the compound devices (e.g., MESFETs, HBTs, HEMTs, PHEMTs, etc.), forming an electrical connection therebetween.

Abstract: A digital frequency synthesizer includes a clock which produces a clock signal oscillating at a fixed frequency and a delay line which receives the clock signal and which produces therefrom a plurality of phase shifted clock signals oscillating at the fixed frequency. Each phase shifted clock signal is shifted in phase with respect to the clock signal and with respect to the other phase shifted clock signals. A look-up table receives an address value related to an ideal phase shifted clock signal oscillating at the fixed frequency and outputs a tap address related to the address value. A selection circuit receives the plurality of phase shifted clock signals and the tap address and outputs one of the phase shifted clock signals in response thereto. A sampling circuit samples at least a portion of the one phase shifted clock signal output by the selection circuit and outputs the sampled portion to form at least a part of an oscillator signal having a desired frequency.
