Laser diode driving circuit |
摘要 |
A laser diode driving circuit is provided, which is capable of supplying a laser diode thereof with a high-speed pulse current. A current source supplies a current to the laser diode. An NMOS transistor as a first switch is connected between the current source and the laser diode. An NMOS transistor as a second switch is connected between a junction between the current source and the first switch and a pseudo load. A controller supplies a first voltage pulse signal to the first switch and a second voltage pulse signal opposite in phase to the first voltage pulse signal to the second switch to switch the first and second switches in a complementary manner.
