Current-mode AC-coupled optical driver device

An optical driver device for driving a light emitting device, the optical driver device comprising:

• a coupling capacitor for coupling an output of the optical driver device to the light emitting device, the coupling capacitor having a first node configured to couple to the light emitting device;
• a high-frequency current-mode driver having a first output coupled to a second node of the coupling capacitor-frequency current-mode driver including a first switching circuit configured to generate a first current, the high-frequency current-mode driver configured to utilize a first current source for generating the first current;
• and
• a low-frequency current-mode driver having a second output coupled to the first node of the coupling capacitor, the low-frequency current-mode driver including a second switching circuit configured to generate a second current, the coupling of the second output to the first node of the coupling capacitor providing a path for the second current to the light emitting device that bypasses the coupling capacitor, the low-frequency current-mode driver configured to utilize a second current source for generating the second current.
