Zusammenfassung: | The present invention relates to a high-speed optical communication LED driver based on a linear modulation, which is a light emitting diode driving circuit (101) for an optical transmitter (100), comprising: a high-speed signal path (102) including a high-speed transconductance amplifier (114) configured to linearly convert an input signal into an output signal for a linear modulation of a light emitting diode (110); and a low frequency control path (103) configured to generate a transconductance (115) in accordance with a low frequency component of the input signal (106). The light emitting diode driving circuit (101) for the optical transmitter (100) is configured to allow the low frequency control path (103) to control a transconductance (116) of the high-speed transconductance amplifier (114).
