Abstract: In order to provide a circuit arrangement and a method for controlling and measuring a current in at least one charge element, in particular in at least one laser diode, which can be used at a low operating voltage with laser current control and/or at a low drop in voltage, also for so-called “low power” applications, it is proposed to couple three MOSFETs in a split manner for a charge path and for two measurement paths and to maintain the three MOSFETs by means of an auxiliary controller at the same working point such that they deliver the modulation current and comparison currents fixed with respect to the modulation current. The comparison currents are used to determine the average modulation current and feed a control device which delivers these currents—and thus also the average modulation current—to a desired value in which an operational or control voltage is varied on a circuit block by the control device. The circuit block delivers output signals depending on the operational or control voltage in the amplitude, said output signals controlling two or more circuit elements in the charge path and the measurement paths.

Abstract: Enabling Low Frequency Periodic Signalling over an optical link with a circuit arrangement and method for controlling a light-emitting component, including: monitoring a differential input for the presence of an electrical idle state by an IDLE detector; triggering a time delay block by the IDLE detector when the electrical idle state at the differential input is interrupted or resumed; detecting whether the differential input is driven by a Low Frequency Periodic Signalling or by a Super Speed/Enhanced Super Speed signalling by a signal type detector; making a decision whether the signalling is to be transmitted by a decision circuit; an input stage connected to the decision circuit; and driving the light-emitting component by an output stage.
