Abstract (en)
[origin: US2015286238A1] A reference voltage generation circuit, including a first current source in series with a first bipolar transistor; a second current source in series with a first resistor; a third current source in series with a second bipolar transistor, the third current source being assembled as a current mirror with the first current source; a second resistor between the base of the second bipolar transistor and the junction point between the current source and the first resistor; and a fourth current source in series with a third resistor, the junction point between the fourth current source and the third resistor defining a reference voltage terminal.
