摘要：
This invention relates to a light emitting diode driving circuit (101) for use in an optical transmitter (100) comprising: a high-speed signal path (102) comprising a high-speed trans-conductance amplifier (114) configured for a linear transformation of an input signal to an output signal for linear modulation of a light emitting diode (110), and a low-frequency control path (103) configured for generating a trans-conductance (115) in dependence of a low-frequency component of the input signal (106), and wherein the low-frequency control path (103) is configured for controlling the trans-conductance (116) of the high-speed trans-conductance amplifier (114).
