PURPOSE: A temperature independent reference circuit is provided to reduce total area by replacing a resistor R4 with a transistor MP5. CONSTITUTION: A base and collector of a first bipolar transistor are connected to a base of a second bipolar transistor. First and second resistors are connected between the emitter of the second bipolar transistor and a ground potential. The first and second resistors have first and second resistance values, R1 and R2, and third and second temperature coefficients, TC3, and TC2, respectively. A current mirror is connected to the first and second bipolar transistors.
