ABSTRACT:
A voltage generating circuit includes a first current source which generates a first current and a first voltage generating circuit which generates a first voltage having a first temperature dependency. A second voltage generating circuit generates a second voltage having a second temperature dependency different than the first temperature dependency. A voltage adder circuit coupled to the first and second voltage generating circuits adds the first and second voltages to generate a third voltage having no temperature dependency. A voltage replicating circuit coupled to the voltage adder circuit coupled to the voltage adder circuit replicates the third voltage as a fourth voltage having a level corresponding to the third voltage. A second current source generates a constant second current through a resistive element biased by the fourth voltage and a current replicating circuit coupled to the first and second current sources replicates the second current as the first current.
