    Abstract: A semiconductor device having a first circuit block supplied with a first operating voltage, a second circuit block supplied with a second operating voltage, a voltage generating circuit for generating a third operating voltage in response to the first operating voltage, and a third circuit block supplied with the third operating voltage. Preferably, the third operating voltage is generated such that the first operating voltage is increased to a fourth operating voltage by a voltage-up converter, and then the fourth operating voltage is dropped to the third operating voltage by a voltage down-converter. Hence, a power supply operating internally stably in spite of use of a relatively fluctuating voltage can be provided even in the case where a power-supply voltage is dropped.

    Abstract: The invention intends to provide a technique that achieves a sufficient phase margin with ease. The circuit includes a power supply circuit that is formed with a phase compensating resistor and a phase compensating capacitor, between a second input terminal of a differential amplifier and a low supply voltage. Thereby, the first pole frequency in the overall gain is determined by the first pole frequency in the voltage-dividing resistor stage in the Bode diagram for the pole/zero compensation, which is shifted to a lower frequency. Also, the zero point cancels the first pole frequency in the differential amplifier stage, which reduces the phase delay to secure the phase margin. And, since the phase compensating resistor can take a considerably high resistance, the same characteristic can be achieved with a low capacitance of the phase compensating capacitor; thereby, the phase compensation becomes possible with a resistor and a capacitor having a smaller size than the pole/zero compensation with the internal supply voltage.

    Abstract: A first clamp circuit and a second clamp circuit stacked thereon in vertical respectively for clamping unwanted level voltages are provided between the high potential side power source and low potential side power source and an intermediate node formed by vertical stacking of the first clamp circuit and second clamp circuit is coupled with the power source for internal circuit. Since a capacitor originally provided in the internal circuit is allocated in parallel to the first clamp circuit, impedance is reduced due to existence of the capacitor and potential difference due to over-current flowing in the chip is reduced. Accordingly, potential difference due to over-current flowing into the chip may be reduced and static electricity dielectric strength can be improved by allowing higher over-current. Thereby, impedance when the clamp circuits are stacked in two stages.
