  • Circuit generating a stable reference voltage with respect to temperature, particularly for CMOS processes
    Patent number: 6552602
    Abstract: It is described a circuit generating a stable reference voltage with respect to temperature, which circuit is connected between first and second voltage references and comprises at least one current generating circuit adapted to inject a reference current into a resistive element connected between a base terminal of a bipolar transistor and an additional voltage reference. The bipolar transistor is connected between the first and second voltage references and to an output terminal of the generator circuit whereat the stable reference voltage with respect to temperature is. The generator circuit further comprises at least another resistive element, feedback connected between the output terminal of the generator circuit and the base terminal of the bipolar transistor to enable injecting additional current, having reverse dependence on temperature from the reference current, into the resistive element.
