摘要： A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q1, Q2) having emitter terminals at the same electric potential. A base terminal of Q1 is disposed on a collector side of Q2. A first resistance element connects the collector side of Q2 with the base side of Q2; and a second resistance element (R1) connects a collector side of Q1 to R2. A third resistance element (R3) connects a base terminal of Q2 with the electric potential of the emitter terminals. An amplifier (A1) outputs a voltage based on a voltage difference between the collector sides of Q1 and Q2; and a voltage-current converting section (MP1, MP2) converts amplifier output into a current supplied to the connection node of R1 and R2. A voltage is then output on the basis of the generated current.

摘要： Occurrence of power supply noise arising in connection with a step-down action at the time of turning on power supply is to be restrained. A step-down unit is provided with a switched capacitor type step-down circuit and a series regulator type step-down circuit, and stepped-down voltage output terminals of the step-down circuits are connected in common. The common connection of the stepped-down voltage output terminals of both step-down circuits makes possible parallel driving of both, selective driving of either or consecutive driving of the two. In the consecutive driving, even if the switched capacitor type step-down circuit is driven after driving the series regulator type step-down circuit first to supply a stepped-down voltage to loads, the switched capacitor type step-down circuit will need only to be compensated for a discharge due to the loads, and a peak of a charge current for capacitors can be kept low. When operation of the switched capacitor type step-down circuit is started, no large rush current arises, and occurrence of noise is restrained.

摘要： A semiconductor integrated circuit device with reduced consumption current is provided. A first step-down circuit stationarily forms internal voltage lower than supply voltage supplied through an external terminal. A second step-down circuit is switched between first mode and second mode according to control signals. In first mode, the internal voltage is formed from the supply voltage supplied through the external terminal and is outputted through a second output terminal. In second mode, operating current for a control system that forms the internal voltage is interrupted and an output high impedance state is established. The first output terminal of the first step-down circuit and the second output terminal of the second step-down circuit are connected in common, and the internal voltage is supplied to internal circuits.

摘要： A constant current is formed by supplying voltage differences between bases and emitters of a first transistor which allows a first current to flow in the emitter thereof and a second transistor which allows a second current having a current density larger than a current density of the first transistor to flow in an emitter thereof to a first resistance. A second resistance is provided on a ground potential side of a circuit in series with the first resistance. A third and a fourth resistances are provided between collectors and the power supply voltages of the first transistor and the second transistor. Both collector voltages of the first and second transistors are supplied to a differential amplifier circuit having the CMOS constitution thus forming an output voltage and, at the same time, the output voltage is supplied to bases of the first transistor and the second transistor in common.
