Abstract
A circuit to provide a burn-in reference voltage that is stable with respect to temperature and manufacture. The burn-in reference voltage circuit produces a burn-in reference voltage related to an external reference voltage. The circuit includes a feedback circuit to produce a feedback voltage that tends to the internal reference voltage in response to a deviation of the feedback voltage, from the internal voltage. The feedback voltage is mirrored to produce a mirrored voltage having the same magnitude as the feedback voltage but measured with respect to the external reference voltage.
