DC-coupled laser drive circuit and method for driving laser diode device
摘要:
A DC-coupled laser drive circuit (1) includes (i) a voltage drop section (14) provided between a power source and a pre-driver (12) and (ii) a voltage drop amount controlling section (16) for controlling, according to an output of the pre-driver (12), an amount of a voltage drop in the voltage drop section (14).
