Abstract
A bandgap voltage circuit with a first circuit to generate an output voltage as a sum of a first voltage with an amplitude that is proportional to absolute temperature, and a first feedback voltage with an amplitude that is complementary to absolute temperature, a second circuit to generate a voltage having an amplitude that is complementary to absolute temperature, a scaling circuit to generate a second feedback voltage with an amplitude that is a fraction of the voltage of the control terminal, and a regulator circuit to regulate the first feedback voltage according to the second feedback voltage by controlling a first input current of the first circuit and a second input current of the second circuit.
