Abstract
In order to be able to receive any digital optical signals in the bandwidth range from zero bits per second to the high Gbits/second range with as little circuit complexity as possible and to be able to process said signals with the least possible energy requirement for reprocessing, the invention proposes a circuit arrangement as well as a method for receiving digital optical signals by means of at least one light-receiving component connected upstream of at least one signal input port, particularly by means of at least one photodiode, wherein the unipolar current signal coming from the light-receiving component through the signal input port is transformed into a bipolar current signal by means of a compensation current provided by at least one current source, the value of said current being defined by means of at least one digital register.
