Title:
LASER DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/218687
Kind Code:
A1
Abstract:
Disclosed in the present application is a laser drive circuit, relating to the technical field of circuits. The laser drive circuit comprises: a drive circuit and an impedance conversion circuit; the drive circuit is used for receiving an initial voltage signal, converting the initial voltage signal into a target voltage signal, and outputting the target voltage signal to the impedance conversion circuit; the impedance conversion circuit is used for converting the target voltage signal into a target current signal, and providing the target current signal to an electro-optical converter, the target current signal comprising an alternating current working signal and a direct current bias signal, and the direct current bias signal being used for providing a static working point current of the electro-optical converter. The present application solves the problem in the prior art of the low degree of integration of laser drivers.
