    Abstract: PURPOSE: To provide a circuit that generates a reference voltage with negative temperature coefficient together with a band gap reference voltage with positive temperature coefficient. CONSTITUTION: This circuit includes a network consisting of a Vbe voltage multiplier circuit (K'Vbe) circulating a properly stabilized current against change in a supply voltage between an output node A of an amplifier and a band gap voltage generating network, at least one resistor R connected between a band gap voltage node and ground, and resistive voltage dividers R1, R2 connected to between an output node and ground.

    Abstract: A bandgap voltage reference circuit employs a Vbe voltage multiplier network in a feedback line of an output amplifier of the bandgap reference circuit, thus permitting to independently fix the output voltage that is produced and the temperature coefficient thereof. A voltage reference having a linear negative temperature coefficient in an extended temperature variation range may be obtained, starting from a bandgap reference voltage with a positive temperature coefficient.
