Abstract
A monolithically integratable current adding circuit includes a current mirror circuit, the input port of which forms a first input terminal of an adding circuit and the output port of which is connected, via two series connected resistors, to a voltage reference. The point of connection between these series connected resistors forms a second input terminal of the adding circuit. The adding circuit also includes a voltage to current converter which has a first and second input terminal connected respectively to the output port of the current mirror circuit and to the voltage reference and which has an output terminal which forms the output terminal of the adding circuit.
