Patent ID: 8125264

Claim:
A voltage generation circuit comprising: a minimum voltage setting circuit connecting to a first node; a voltage setting circuit including a first voltage setting circuit that has a plurality of resistive elements of a resistance value of (½) n of a resistance value which is to be a reference and a plurality of gate transistors and a second voltage setting circuit that has a plurality of resistive elements of the same resistance value as a resistance value which is to be a reference and a plurality of gate transistors, and one end of the first voltage setting circuit connecting to the first node and one end of the second voltage setting circuit connecting to the first node; a differential amplifier that has two input terminals and one output node, one input terminal is input with a reference voltage, the other input terminal is connected to the first node and the output node outputs a result of a comparison of voltages input from the two input terminals; a pump control circuit that is input with the result of the comparison of voltages and outputs a control signal controlling a charge-pump motion; and a charge pump circuit that outputs the voltage by the control signal.
