Title:
CIRCUIT CONFIGURATION AND METHOD FOR RECEIVING DIGITAL OPTICAL SIGNALS
Document Type and Number:
WIPO Patent Application WO/2013/174376
Kind Code:
A3
Abstract:
In order to be able to receive any digital optical signal (S) 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 specifies a circuit configuration (E) and a method for receiving digital optical signals (S) by means of at least one light-receiving component (PD) connected upstream of at least one signal input port (PIN-Signal), particularly by means of at least one photodiode, wherein the unipolar current signal (IPD) coming from the light-receiving component (PD) through the signal input port (PIN signal) is transformed into a bipolar current signal (IPD-IDC) by means of a compensation current (IDC)provided by at least one current source (IDAC), the value of said current being defined by means of at least one digital register (MM, MC).
