  • Voltage reference circuit with programmable thermal coefficient
    Patent number: 5731696
    Abstract: A voltage reference circuit with programmable thermal coefficient, comprising first and second bipolar transistors having their base terminals connected together and collector terminals connected to two legs of a current mirror circuit. The emitter terminal of the first transistor is connected to ground through two resistors in series with each other, and the emitter terminal of the second transistor is connected to a node between the two resistors. The emitter of at least one of the two transistors has discrete portions adapted to be connected electrically together in a predetermined fashion.
