Abstract
A bandgap reference generation circuit in an integrated circuit (IC) and method for generating a bandgap reference voltage are disclosed. The bandgap reference generation circuit includes a first proportional to absolute temperature (PTAT) current generation section for generating a PTAT current component, a current circuit configured to generate a trimmed PTAT current component substantially invariant of sheet resistance of at least one resistor in the current circuit, and a complementary to absolute temperature (CTAT) current generation section including a diode on which the trimmed PTAT current component is fed to generate a CTAT current component. A combination of the PTAT and CTAT current components generate the bandgap reference voltage.
