BAND GAP VOLTAGE REFERENCE GENERATOR CIRCUIT, THERMAL SENSING CIRCUIT, AND INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a band gap voltage reference generator in which a trimming circuit configuration is not required.;SOLUTION: The band gap voltage reference generator circuit includes a reference voltage generator unit 804. The reference voltage generator unit 804 includes a first output current source circuit 124, and a first resistor 136 that is linked to the first output current source circuit 124. Between the first resistor 136 and the first output current source circuit 124, a first voltage reference output node N3 is disposed for generating a first reference voltage Vref1. The reference voltage generator unit 804 also includes a second resistor 138 that is linked to a negative voltage feeding part 152. Between at least one of a second output current source circuit 126 linked to a positive voltage feeding part 150 and the first resistor 136, and the second resistor 138, a second voltage reference output node N5 is disposed for generating a second reference voltage Vref2.;COPYRIGHT: (C)2005,JPO&NCIPI
