摘要： A crystal oscillation circuit has a reduced circuit area and enables to stably oscillate at low consumed current. The crystal oscillation circuit includes an oscillating amplifier and a constant voltage generator. The oscillating amplifier excites a resonator composed of a resistor, a crystal oscillator and a capacitor. The constant voltage generator includes a one-stage differential circuit composed of a transistor and a capacitor for suppressing transient fluctuation of a constant voltage Vreg for generating the constant voltage Vreg served as a supply voltage for the oscillating amplifier. By generating the constant voltage Vreg through the one-stage differential circuit, the phase lag of the constant voltage Vreg reaches 90 degrees at most. This eliminates the necessity of a phase compensation capacitor, resulting in making the circuit area smaller and realizing the stable oscillation at low consumed current.

摘要： A semiconductor device is disclosed including a current generator circuit that generates a first current substantially proportional to an absolute temperature, the first current being determined by a size ratio of a MOS transistor, and by a resistor; and a starting-up circuit that causes the current generator circuit to generate the first current at a stable working point of the current generator circuit, wherein while the current generator circuit operates at the stable working point, a current that flows through the starting-up circuit is determined by a diffusion resistance and a MOS transistor. When the current generator circuit starts operating at a stable operating point, resistance of the diffusion resistor and a MOS transistor connected in series determines a current that flows through a starting-up circuit. According to the above arrangements, the power consumption of the circuit can be reduced by increasing the resistance of the diffused resistor.

摘要： A clock modulator for in-vehicle electronic equipment requiring an EMI countermeasure optimally reduces undesired radiant noise by a low spectral dispersion number. A delay circuit has delay buffers DB0 to DB30 connected in series with each other, each outputting an output pulse delayed from an input pulse by a phase delay time &tgr;, and a selection circuit sequentially selecting an output pulse outputted from each of the delay buffers DB0 to DB30. Adjustment is made such that with respect to an input CLK inputted to the delay buffer DB0, a phase variation amount of the output pulse from the delay buffer DB0 and a phase variation amount of the output pulse from the delay buffer DB30 are near ±45° when a phase of the output pulse from the delay buffer DB15, at a center position of the delay buffers DB0 to DB30, is made a reference.

摘要： Even when, for example, electric charge is injected into the output transistor due to external factor such as a noise from the outside, to prevent the step-down voltage from rising, the step-down circuit is comprised of an N channel type output transistor which controls the voltage at the control end, a booster, which is connected to the control end of the output transistor and raises the voltage at the control end and a discharge circuit, which discharges the electric charge at the control end of the output transistor so that the power supply voltage inputted from the input end is stepped down to a desired step-down voltage and outputted from the output end.
