发明名称 High voltage generating circuit improved in parasitic capacitance of voltage-dividing resistance
摘要 <p>The present invention provides a circuitry comprising : a first circuit for rising a voltage level, the first circuit having an output terminal connected to a high voltage output line for outputting a high voltage output ; a comparator having an output terminal connected to an input side of the first circuit, the comparator further having a first input terminal and a second input terminal for receiving a reference voltage ; and a voltage dividing circuit connected between the high voltage output line and a low voltage line having a substantially fixed lower potential than the high voltage output line, the voltage dividing circuit having an output node which is connected to the first input terminal of the comparator for outputting a divided voltage output; and the voltage dividing circuit having at least a resistance between the output node and the high voltage output line, wherein a parasitic capacitance of the at least resistance between the output node and the high voltage output line is connected to the high voltage output line. &lt;IMAGE&gt;</p>
