Laser circuits are disclosed herein that include, in one example, a proxy laser drive cell and a proxy comparator circuit for deriving a laser driver bias control using one or more constant current supplies. Comparator circuits are disclosed that are adapted to generate an output based on a proxy voltage having first and second voltage components wherein one of the voltage components is developed based on one or more constant current supplies indicative of laser control current.
