Patent number: 6710669Abstract: To provide a voltage controlled oscillator having a large variable width of oscillation frequency while ensuring oscillation starting performance, a P-channel MOS transistor Tr is made ON by detecting that an oscillation signal is provided with a predetermined amplitude value and oscillating operation is shifted from an initial state to a steady state by a detecting circuit OPC and a capacitor CA is connected in series with a series circuit constituted by a crystal resonator XL and a varicap diode CV. In the initial state, a load capacitance is reduced to thereby cancel an amount of reducing conductance gm of an oscillation amplifying portion to correspond to operation of the crystal resonator by a low amplitude and negative resistance necessary for maintaining excellent oscillation starting performance is provided and in the steady state, a width of changing the oscillation frequency is enlarged by enhancing an effect of the varicap diode CV.Type: GrantFiled: April 29, 2002Date of Patent: March 23, 2004Assignee: Nippon Precision Circuits Inc.Inventors: Eiichi Hasegawa, Kazuhisa Oyama

Patent number: 6690245Abstract: An oscillation control circuit is offered which can improve the startability of an oscillator circuit operating at high frequencies and at a low power-supply voltage. When the oscillation potential of the oscillation signal is between the inversion potential (1.2 volts) of a CMOS inverter IV1 and the inversion potential (1.8 volts) of a CMOS inverter IV2, the logical output value of a CMOS Schmitt inverter SI1 is 1. The output of a CMOS inverter formed by MOS transistors T32 and T33 is shorted out via a MOS transistor T34. Its logical output value is kept at 1. When the inversion potential of the CMOS inverter IV1 or the inversion potential of the CMOS inverter IV2 is exceeded, if the input voltage to the CMOS Schmitt trigger SI1 increases above its inversion potential (1.8 volts), the logical output value assumes a value of 0. The CMOS inverter formed by the MOS transistors T12 and T13 is first set into operation. The oscillation signal is inverted, setting a circuit LA at a later stage into operation.Type: GrantFiled: November 29, 2001Date of Patent: February 10, 2004Assignee: Nippon Precision Circuits Inc.Inventors: Eiichi Hasegawa, Kazuhisa Oyama, Masahisa Kimura

Patent number: 6556094Abstract: An oscillator circuit adapted for a piezoelectric oscillator which has a weak oscillation output for generating high frequencies is provided. The speed of operation of the oscillator circuit is increased. An integrated circuit for such an oscillator circuit is also provided. The oscillator circuit has an amplifier portion consisting of CMOS inverters connected in cascade. MOS transistors forming the CMOS inverters have channel widths that decrease successively from the first stage to the last stage to improve the amplification factor of the amplifier portion at high frequencies. This makes it possible to amplify weak oscillation output from the quartz oscillator (XL). A filter circuit produces a peak of negative resistance at a frequency higher than conventional. This permit oscillation operation at higher frequencies.Type: GrantFiled: October 26, 2001Date of Patent: April 29, 2003Assignee: Nippon Precision Circuits Inc.Inventors: Eiichi Hasegawa, Masahisa Kimura, Kazuhisa Oyama, Kunihiko Tsukagoshi
