  • Publication number: 20180331499
    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.
