Abstract:
An on chip temperature independent current generator for generating a temperature independent current, said temperature independent current generator including: an on chip current generator having an output to provide an electrical current being proportional to an absolute temperature of a chip in which the temperature independent current generator is embedded; and an on chip transistor having a base connected to a temperature independent reference voltage generator, a collector connected to a current mirror, and an emitter connected to the output of the on chip current generator and connected via an on chip resistor to a reference potential, wherein the current mirror is adapted to mirror a collector current flowing to the collector of said on chip transistor to generate the temperature independent current.
