摘要： There is provided an oscillator circuit capable of obtaining stable frequency by avoiding output having unstable frequency that is likely to occur to an operation/stop-control-feasible type oscillator circuit when oscillation begins. In such an oscillator circuit, an oscillation permitting signal (EN) sets an oscillator section in oscillation-operable state, whereby a controller section starts operation. The controller section that has stared its operation change an oscillation-frequency control signal (VR) into a signal value corresponding to predetermined oscillation frequency so as to set oscillation frequency at an oscillator section. Further on, the oscillator section outputs an oscillation signal in response to a detection signal (MON) that is outputted after a detector section compares a signal inputted therein with a predetermined signal value and detects that the inputted signal reaches a predetermined signal value. Thereby, transient state of an oscillation-frequency control signal (VR) can be detected. That is, there can be avoided an output of an unstable oscillation signal due to a transient oscillation-frequency control signal (VR).

摘要： An excluding unit is controlled by a control signal received from a control unit, and based on the control signal a determination is made for each of circuit blocks as to whether either a voltage signal at a position of its corresponding circuit block or a signal indicating a voltage is outputted to a selection unit. From a circuit block which is not in operation, the voltage, but not a voltage signal at a position of the circuit block, is outputted to the selection unit. By this, the circuit block which is not in operation cannot be judged to have voltage drop, and accordingly, a high supply voltage cannot be supplied. Consequently, a malfunction caused by supply voltages to other circuit blocks being too high does not occur.

摘要： The present invention aims to provide a multi-power supply circuit capable of generating multi-power efficiently and reducing power consumption, and a multi-power supply method therefor. A supply voltage is output from a DCDC converter. Output transistors of linear regulators are series-connected to a power supply path between a resistive element and the DCDC converter. That is, a bias current path is shared between the linear regulators and the corresponding path is taken as one. With the supply voltage as the reference, supply voltages corresponding to intermediate negative voltages between the supply voltage and a reference voltage are generated by the linear regulators. A bias current consumed by the multi-power supply circuit is held constant as a bias current i regardless of the number of the linear regulators.
