Abstract
A low voltage bandgap reference circuit () is provided which includes a first current generator () having first and second circuit branches which include, respectively, first and second bipolar transistors having different sizing reference values for generating a first current at a first resistor that varies proportionally as a function of temperature; a second current generator () having a third circuit branch which includes one or more field effect transistors and no bipolar transistors for generating a second current that varies inversely as a function of temperature; and a third circuit () connected to generate a bandgap reference current in response to the first current and the second current.
