Abstract

An integrated circuit configuration for generating a reference current by bipolar technology includes a transistor of one conduction type having a control terminal being acted upon by a reference voltage and having a load path. An externally connectable resistor is to be connected between the load path of the transistor and a reference potential. A current mirror configuration has an input side connected between the load path of the transistor and a supply voltage source and has an output for picking up a reference current.
