REFERENCE-VOLTAGE CIRCUIT

摘要

Provided is a reference-voltage circuit capable of adjusting to any temperature characteristic at any output voltage. The present invention is provided with: a reference-current-generating circuit for converting into a current the difference between forward voltages of a plurality of PN junction devices and generating a first current; a current-generating circuit for generating a second current using the first current generated by the reference-current-generating circuit; and a voltage-generating circuit having a first resistor in which the flow of the first current generates a first voltage having a positive temperature characteristic, and a second resistor in which the flows of the first current and the second current generate a second voltage having a negative temperature characteristic. The present invention is configured so that a reference voltage obtained by adding the first voltage and the second voltage is outputted.
