Abstract :
In this paper, we proposed a high speed and large current laser diode driving circuit with low sensitivity to process variation. It is commonly applied in the DVD player. In a large current and high speed output LDD circuit, topics such as overshoot, undershoot, rising time, falling time and slew-rate are necessary to be considered. Therefore, to improve the signal integrity of Combination Switch Mode (CSM) LDD Architecture, modification is made. The simulation results show that the output current turned slightly slower in speed, whereas the performance in overshoot and undershoot are significantly improved. Finally, we proposed the Source Degeneration Type with Improve Overshoot Performance (CSM) LDD Architecture. The circuit has been implemented in 0.35-μ m 5V CMOS process and simulated by HSPICE.
