Beschreibung
Zusammenfassung:	A driver electronic circuit for a pulse amplitude modulation transmitter includes a plurality of transmission lanes. Each transmission lane is configured to independently generate a current output corresponding to data input into each transmission lanes. The driver electronic circuit also includes a summing node configured to sum the output currents from the plurality of transmission lanes. The driver electronic circuit further includes one feedback loop circuit coupled to the plurality of transmission lanes configured to control the currents of each said current outputs. The driver electronic circuit may be configured to drive a vertical-cavity surface-emitting laser for optical communication.
