  • Patent number: 6859085
    Abstract: A mixer circuit is composed of a differential amplifier circuit and a DBM circuit. The differential amplifier circuit has a first bipolar transistor, a second bipolar transistor, a first resistor provided between the respective bases of the first and second bipolar transistors, and a capacitor provided between the base of the second bipolar transistor and the ground. Since the first resistor and the capacitor are provided such that the circuit undergoes RC oscillation in response to the third harmonic of an input signal, the third and higher-order harmonics can be reduced.

  • Patent number: 6593601
    Abstract: When forming first and second circuits on a semiconductor substrate, an isolation region is provided between the first and second circuits by embedding a conductor in the semiconductor substrate. Also, an output node of a low impedance voltage output circuit that provides a fixed voltage at low impedance is connected to the isolation region. In this way, a noise current caused by high-frequency noise generated from the first or second circuit flows into the low impedance voltage output circuit. Hence leakage of noise signals between the circuits can be suppressed.

  • Patent number: 6163107
    Abstract: A field emission cathode that can uniform the number of electrons emitted from each emitter and can prevent a line defect even when a gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode, so that the current supplied from the cathode electrode to the emitter can be controlled. If the emitter is short-circuited with the gate electrode, the increased current density destroys the channel, so that the current supply to the emitter can be stopped.

    Abstract: An RF-driven semiconductor chip is die-bonded to the top face of a metal plate. The semiconductor chip and the metal plate are molded together with outer leads in a plastic package in the form of a rectangular parallelepiped. The metal plate is exposed at the back face of the plastic package. The metal plate is not protruding from the front and rear side faces of the plastic package. The front and rear side faces of the metal plate are flush with the front and rear side faces of the plastic package and partially exposed at the front and rear side faces of the plastic package. The front and rear portions of the plastic package are centrally formed with respective cutaway portions each in the form of a rectangular parallelepiped. The top face of the metal plate is exposed in the cutaway portions formed centrally in the front and rear portions of the plastic package to form solder portions.

  • Patent number: 5866438
    Abstract: In a comb-like or wedge-like electron emitting device, an emitter or both an emitter and an anode electrode are processed from a single-crystal silicon thin film of an SOI wafer. The single-crystal silicon thin film in portions other than the processed portion is removed so that the silicon oxide layer is dug down further slightly. A gate electrode for applying an electric field in order to draw electrons out of the emitter is provided in the dug-down portion. When the end and side faces of the emitter are formed as (111) faces by anisotropic etching in the condition that the single-crystal silicon thin film is oriented to a (100) face, the emitter has a sharp edge at about 55.degree. with respect to the substrate. In a conical electron emitting device, the gate electrode is constituted by a single-crystal silicon thin film of an SOI wafer so that a pyramid surrounded by the (111) faces is formed on the single-crystal silicon substrate.
