Abstract :
This paper presents high-speed and area-efficient laser-diode driver with interwoven inductor in a 0.18-μm CMOS. We interweave ten peaking inductors for area-effective implementation as well as performance enhancement. Interwoven inductor can not only achieve area-efficiency but also tune frequency characteristic. Mutual inductances of interwoven inductor enhance bandwidth and suppress group delay dispersion. The test chip area is 0.32 mm2 and the maximum operating speed is 25 Gb/s.
