Abstract
The present disclosure provides a hybrid-mode laser drive circuit and an optical emitting system. An equalizer circuit is configured to generate, according to a data signal and a clock signal, an equalization signal for compensating a hybrid-mode laser drive circuit; the hybrid-mode laser drive circuit is connected to an output end of the equalizer circuit, and is configured to generate a corresponding drive signal according to an output signal of the equalizer circuit, so as to drive a light emitting diode to generate a corresponding optical signal; a third current source is connected between a power supply voltage and an output end of the hybrid-mode laser drive circuit; an anode of the light emitting diode is connected to the output end of the hybrid-mode laser drive circuit and a cathode of the light emitting diode is connected to a power supply ground.
