Abstract
A method and apparatus for powering up and powering down a laser diode and its driver are disclosed. The disclosed method and apparatus enable the use of deep sub-micron CMOS technology to build a laser diode driver (LDD), while ensuring the low voltage limits prescribed by such technology are not exceeded. Building an LDD with deep sub-micron CMOS technology pushes circuit integration further ahead, bringing cost of LDDs and required board circuits down.
