Abstract
A passive peaking circuit is formed in part from a passive step-down impedance transformer that interconnects the light source driver to the light source. The step-down impedance transformer has impedance that decreases in a continuous or discrete manner in the direction from the light source driver circuit to the light source. The passive peaking circuit peaks the electrical drive signal being delivered from the light source driver circuit to the light source, thereby widening the eye opening.
