Abstract
A laser drive and control system which provides protection for a laser diode by preventing excess current from a power source, that normally supplies power to the laser diode, from destroying the laser diode when the voltage supplied by the power source to the laser diode decreases below a certain voltage which causes excess current. The system is implemented in CMOS circuitry for miniaturization into an integrated circuit chip.
