After careful and considered review, it has been determined that the above paper is in violation of IEEE's Publication Principles.

Specifically, the paper contains information that Adrian Maxim admits had been falsified. In response to an inquiry on this misconduct, Mr. Maxim acknowledged that the following people who have been listed as co-authors on several of his papers are fabricated names and that he is the only author:

C. Turinici, D. Smith, S. Dupue, M. Gheorge, R. Johns, D. Antrik

Additionally, in papers by Mr. Maxim that have co-authors other than those listed above, it was discovered in some cases that he had not consulted with them while writing the papers, and submitted papers without their knowledge.

Although Mr. Maxim maintains that not all of the data is falsified, IEEE nevertheless cannot assure the integrity of papers posted by him because of his repeated false statements.

Due to the nature of this violation, reasonable effort should be made to remove all past references to the above paper, and to refrain from any future references.
A low supply voltage fully-integrated 12.5Gb/s laser diode driver IC was realized in a 0.2μm 60GHz f_T SiGe BiCMOS process. A three-fold power consumption reduction versus existing drivers was achieved by using a 3.3V supply and dynamic emitter followers having a local positive feedback loop that boosts the drive strength without taking additional supply power. Low voltage operation was achieved by replacing the tail current source of the output switch with a resistor and setting the current with a common-mode feedback loop. A direct on-chip summation of bias and modulation currents was realized by using a bias modulation canceling circuit. Laser diode driver IC specifications include: 3-3.6V supply voltage, <70mA supply current (excluding output current), 20-100mA modulation current range, 1-100mA bias current range, <12ps_p-p deterministic jitter and 1.5×1.5mm² die area.
