ARBITRARY WAVEFORM GENERATOR TO IMPROVE LASER DIODE DRIVER PERFORMANCE

摘要

An arbitrary waveform generator modifies the input signal to a laser diode driver circuit in order to reduce the overshoot/undershoot and provide a flat-top signal to the laser diode driver circuit. The input signal is modified based on the original received signal and the feedback from the laser diode by measuring the actual current flowing in the laser diode after the original signal is applied to the laser diode.
