ABSTRACT:
A power supply circuit is provided for producing a reference current with a prescribable temperature dependence. The circuit includes two current sinks, which at their respective input take up a first input current (I1) or a second input current (I2), and in which current sinks at their respective outputs are connected to a node having a reference potential, the output of at least one current sink being connected via a resistor to the node having the reference potential. The resistor is formed by least two reference resistors with prescribable temperature coefficients that are preferably different from one another.
