Abstract

A low-power, direct-drive EML driver circuit is provided that reduces power consumption by reducing the amount of current needed to create the necessary voltage swing in the drive signal. In addition, the EML driver circuit has an impedance matching network that has reduced complexity and that can be made at reduced costs compared to the impedance matching network of a typical EML driver circuit.
