STANDARD CMOS COMPATIBLE BAND GAP REFERENCE

摘要

The present invention provides a CMOS low noise band gap reference circuit (10) that outputs a substantially constant reference voltage VREF. Band gap reference circuits of the present invention have an amplifier that includes a differential pair of bipolar junction transistors and a feedback circuit that adjusts it current to compensate for variations in the provide a output reference voltage VREF that is substantially constant over a range of temperature and a range of supply voltage.
