ABSTRACT In a circuit arrangement for providing a current having a controllable temperature coefficient of current, a diffused resistor (334) is used to set up a reference current in a current source (40) which has a temperature coefficient dependent upon the diffused resistor. A current mirror (352, 354, 356) receives the reference current and passes a portion of it through an ion implanted resistor (360). The output current has a temperature coefficient which is a function of the original temperature coefficient of current and a nonzero algebraic multiple of the temperature coefficient of the implanted resistor. By appropriate selection of the resistor values and types, the temperature coefficient of the output current can be set to any desired value.
