Abstract
An optical driver arrangement () comprises a comparator () and a pulse generator (). The comparator () comprises a first input () for receiving a sensed output signal (S) derived from a sensor signal (S) generated by a light sensor (), a second input () for receiving a reference signal (S) and a comparator output () for providing a comparator signal (S). The pulse generator () comprises a control input () coupled to the comparator output () and a generator output () for providing a driver signal (S) to a light source (). The driver signal (S) comprises a series of at least one pulse and a parameter of the driver signal (S) is controlled by the comparator signal (S).
