Abstract:
A proportional to absolute temperature (PTAT) generator, for example, generates a PTAT current (IPTAT) and a VBE (voltage base-to-emitter) in a first regulation loop. A voltage-to-current converter is operable to generate a complementary to absolute temperature current (ICTAT). The IPTAT and ICTAT are summed to obtain a zero temperature coefficient current (IZTC). One ICTAT and one resistor are used to generate the IZTC signal.
