摘要： With a delta sigma modulator of this invention, a plurality of clocks required to control a switching circuit can be easily generated and correlation among phases of the plurality of clocks can be automatically maintained while a frequency of the clocks is modified. A ring oscillator is formed of three delay circuits provided with differential amplifiers in the delta sigma modulator. A clock producing circuit produces the plurality of clocks to control the switching circuit by delaying three-phase clocks outputted from the ring oscillator. All the tail currents Ic in the differential amplifiers in the delay circuits in the ring oscillator and the tail currents Ic in the differential amplifiers in the delay circuits in the clock producing circuit are proportional to each other.

摘要： According to a preferred embodiment of the present invention, a low-voltage operation constant-voltage circuit includes a band-gap reference voltage circuit including a resistor-diode series circuit as a main component. A resistor and a diode-connected bipolar transistor are connected in series to create a constant current. It also includes an output circuit connected in parallel to the resistor-diode series circuit and formed so that the same constant current as the current flowing through the resistor-diode series circuit flows. The output circuit includes a diode-connected MOS transistor, and is configured to cancel the positive temperature coefficient of the current flowing through the output circuit by the MOS transistor. With this, a stable output low-voltage of, e.g., about 0.6 V, excellent in temperature characteristics can be obtained regardless of the ambient temperature changes.
