An unbalanced-balanced SAW filter is configured by providing two cascade-coupled primary-tertiary double-mode SAW filters on a piezoelectric substrate along a propagation direction of a surface wave in parallel and cascade-connecting them, connecting one of electrodes of an IDT of a first double-mode SAW filter disposed at a central portion to a first port Port1, and connecting one of electrodes of an IDT of a second double-mode SAW filter disposed at a central portion to a second port Port2, and connecting the other electrode thereof to a third port Port3. The SAW filter is configured by disposing an electrode near the surroundings of the first port Port1 and the third port Port3 and connecting the electrode to a lead electrode provided at a peripheral edge of the piezoelectric substrate.

摘要： Deterioration in frequency stability with time in a conventional piezoelectric oscillator using an accumulation type MOS capacitance element is improved. A P-channel transistor type or an N-channel transistor type is used as a MOS capacitance element in a variable capacitance circuit used in a piezoelectric oscillator. A bias voltage is applied between P-type or N-type extraction electrodes formed in source and drain regions and an N-type extraction electrode provided in an N-well region or a P-type extraction electrode provided in a P-well region. Instability in the MOS capacitance element with time is thus eliminated.

摘要： Piezo oscillators having a quick start-up circuit, which applies a start-up quickening voltage to the piezo resonator only for a predetermined length of time after the application of power supply voltage, added to a piezo oscillating circuit. The start-up time taken for the piezo oscillators to reach the steady-estate oscillation from the non-oscillating state can be significantly shortened. The phase noise characteristics and frequency stability characteristics are not affected, since the start-up quickening voltage is removed after the predetermined length of time.

摘要： A piezoelectric resonator constituted in one body of an ultrathin vibrating part and a thick annular enclosing part surrounding the vibrating part, in which a groove for an excess adhesive agent, etc., is formed between an appropriate area which is a portion of the surface of the annular enclosing part and on which adhesive is applied, and the inner periphery of a recessed part facing the area, adhesive is applied in the z-axis direction on the peripheral surface of the annular enclosing part to hold the resonator in a package, the resonator is held in the package not by the adhesive but by an elastic claw, or one peripheral part of the annular enclosing part being the surface opposed to a pad positioned in one peripheral part on one of the surfaces of the piezoelectric resonator is bonded to the inner bottom surface of the package. Owing to the holding structures, change of the resonance frequency of the piezoelectric vibrating plate which is caused by flowing of the adhesive into the recessed part is prevented, variation of the temperature-frequency characteristic of the resonator held in the package which is caused in the case of mass production is reduced, and the mechanical strength of the electrical connection by bonding of the piezoelectric resonator incorporated in the package can be improved too.

摘要： A piezoelectric resonator in which an ultra thin vibration part and a thick ring-like surrounding part supporting the periphery of the vibration part are formed in a body. An electrode and an electrode lead pattern extending from the electrode are formed on one side of the vibration part. Another electrode facing the former is formed on the other side of the vibration part except for the region facing the lead pattern. Thus, a capacitance is formed from the mutually facing electrodes and the lead patterns, preventing the increase of the parallel capacitance of the resonator. The reduction of ohmic loss and the suppression of spurious response are realized by making the electrode lead long and narrow, etc. Defect of conduction between the conductive film of the bottom of a package and the electrode of a recessed part is prevented by making a through hole through the ring-like surrounding part in the direction of its thickness and by connecting electrically the electrode lead part extending on one surface of the ring-like surrounding part with the terminal pad provided on the surface opposed thereto via the through hole.
