LOW VOLTAGE BAND GAP REFERENCE GENERATOR |
摘要 |
PURPOSE: A low voltage band gap reference generator is provided to drastically reduce the area occupied by the parasitic bipolar transistor in the band gap reference generator circuit. CONSTITUTION: A low voltage band gap reference generator includes a differential amplifying terminal circuit, a bias circuit, a plurality of current mirror circuit, a plurality of parasitic bipolar circuits and a resistor. The differential amplifying terminal circuit has a negative feed back loop. The bias circuit preforms the bias to the current source circuit in the differential amplifying terminal circuit. The plurality of parasitic bipolar circuits is generated during the CMOS manufacturing process connected to the current mirror circuit. And, the resistor is connected to one of the bipolar transistors. The reference voltage is generated by using the voltage between the resistors.
