Abstract
Disclosed is a system and circuit for a multi-channel optoelectronic device driver. The system and circuit include a differential buffer amplifier, an output driver amplifier, a dedicated voltage regulator, a load compensation circuit, a wave shaping circuit and a laser fault detection circuit. In a multi-channel configuration, each channel has a dedicated voltage regulator such that each channel provides a channel-specific drive signal.
