    摘要: A voltage generation circuit includes a digital type VDC. The digital VDC includes a differential amplify circuit amplifying a voltage deviation of a reference voltage signal from a detection voltage signal to output the amplified voltage to a control node, a signal conversion circuit providing either an H level or an L level according to the voltage level of the control node, and an output transistor connecting an external power supply line and an internal power supply voltage node according to an output voltage of the signal conversion circuit. The center of the range of the varying voltage level of the control node is set by shifting to the logic threshold value of the signal conversion circuit.
