Abstract
The delay and distortion characteristics of an optical detector can be improved with a comparator having tailored offsets and hysteresis. The comparator is controlled by the output of a transimpedance amplifier, coupled in part through a delay mechanism. The delay mechanism provides a dynamic reference level to one terminal of the comparator.
