  • Patent number: 8427227
    Abstract: In one embodiment, a temperature compensation circuit includes a bias circuit configured to output a bias current having a current value increasing in proportion to an absolute temperature in a low-temperature region, and having a greater current value than the current value proportional to the absolute temperature in a high-temperature region, and a transistor which is supplied with the bias current. The bias circuit includes first to third transistors, a fourth transistor through which a first current flows, a fifth transistor, a sixth transistor through which a second current flows, and a control circuit having a connection terminal capable of being connected with an external resistor for adjusting a magnitude of the second current. The bias circuit generates a third current by adding the first current to the second current, and outputs the bias current that is the third current or a fourth current depending on the third current.

  • Patent number: 6611549
    Abstract: A crystal oscillator which configures a voltage controlled oscillator having a variable oscillation frequency is also used as a crystal oscillator of an oscillator for generating a fixed frequency. Control input is integrated by an integrator, a phase of a frequency-divided signal obtained by dividing a fixed clock by a frequency divider is controlled by the integrated value to vary a frequency. Every time a phase-shifting amount at the time becomes to correspond to one clock, a frequency division ratio at dividing the clock is changed from a predetermined frequency division ratio for one time of frequency division to absorb the phase shifting amount for one clock, thereby operating as a voltage controlled oscillator. Thus, the voltage controlled oscillator having the frequency accuracy of a fixed clock is realized.

  • Patent number: 6545557
    Abstract: An FM signal oscillator circuit includes a resonator having a graded- or abrupt-junction variable capacitance diode that is producible through standard IC manufacturing processes but causes an inconstant modulation level. The FM signal oscillator circuit, therefore, is provided with a function of maintaining a constant modulation level irrespective of oscillation frequencies. Namely, to maintain a constant modulation level without regard to oscillation frequencies that change depending on a control voltage applied to the variable capacitance diode, the FM signal oscillator circuit employs a variable gain amplifier whose gain changes in response to the control voltage. The variable gain amplifier amplifies a modulating signal, and the amplified modulating signal is superimposed onto the control voltage.
