  • Precise voltage/current reference circuit using current-mode technique in CMOS technology
    Patent number: 7071767
    Abstract: A voltage/current reference circuit includes a first bipolar transistor and a second bipolar transistor that exhibit a first voltage drop VBE1 and a second voltage drop VBE2, respectively. A first resistor, having a resistance R1, is configured to draw a first current equal to (VBE1?VBE2)/R1. A second resistor, having a resistance R2, is configured to draw a second current equal to VBE1/R2. A first transistor supplies the first and second currents to the first and second resistors. A second transistor, having a current mirror configuration with respect to the first transistor, directly provides a reference current equal to (VBE1?VBE2)/R1+VBE1/R2. A third transistor, having a current mirror configuration with respect to the first transistor, provides a current equal to the reference current to a third resistor having a resistance R3 and a third bipolar transistor that exhibits a third voltage drop VBE3, thereby generating a reference voltage.
