Abstract
Methods, circuits, architectures, apparatuses, and algorithms for determining a DC level in an AC or AC-coupled signal. The method generally includes disabling the AC or AC-coupled signal; sampling the disabled AC or AC-coupled signal to obtain sampled DC values of the AC or AC-coupled signal; and calculating the DC level using the sampled DC values of the AC or AC-coupled signal. The present transmitter generally includes an electro-absorption modulated laser (EML); a photodetector; a signal source configured to provide an AC or AC-coupled signal to the EML; and a microcontroller or microprocessor configured to (i) control the signal source, (ii) receive information from the photodetector, and (iii) deactivate the signal source for a predetermined length of time. The circuits, architectures, and apparatuses generally include those that embody one or more of the inventive concepts disclosed herein.
