A control circuit system for controlling one or more parameters in a circuit with at least one operational stage is disclosed, in the form of a delay stage or a logic stage, the operational stage comprising at least one operational circuit, at least one operational current source for supplying a drive current for the operational stage, and at least one operational load. The operational stage also comprises a number of controllable components of the operational current source and of the operational load, allowing control of the size of the drive current and of the load, respectively, in the operational stage. At least one reference stage includes essentially an image circuit of the operational stage with a reference current source for supplying a drive current for the reference stage and a reference load, comprising a number of controllable reference components, allowing control of the size of the drive current and the load, respectively, of the reference stage. The reference stage, using a reference quantity, controls the currents of the reference and operational current sources to the reference load and the operational load components, respectively.
