Abstract
A device includes a first impedance; a reference current generation circuit configured to generate a reference current according to a first potential difference, a reference voltage, and a first impedance value of the first impedance; a current mirror circuit configured to output an output current having a first ratio to the reference current according to the reference current; a second impedance configured to generate an output voltage according to a second impedance value of the second impedance, a voltage of a first node which is the same as the first potential difference, and the output current; and a negative feedback circuit configured to generate a feedback voltage according to the voltage of the first node, and adjust the output voltage according to the feedback voltage. There is a second ratio that is inversely proportional to the first ratio between the second impedance value and the first impedance value.
