Abstract:
A BGR circuit includes a temperature-proportional current generating part configured to generate a current in proportion to a change in temperature through a plurality of current paths; a temperature-inverse proportional current generating part generates a current in inverse proportion to a change in temperature through a plurality of current paths. An internal voltage reference voltage generating part generates a reference voltage for an internal voltage using the current of the temperature-proportional current generating part and the current of the temperature-inverse proportional current generating part. A temperature voltage output part outputs a voltage corresponding to a change in temperature.
