Title
Area-Effective Inductive Peaking With Interwoven Inductor For High-Speed Laser-Diode Driver For Optical Communication System
Abstract
This paper presents an area-effective bandwidth enhancement technique using interwoven inductors. Inductive peaking is a common practice for bandwidth enhancement, however the area overhead of inductors is a serious issue. We implement six or four inductors into an interwoven inductor. Furthermore parasitics of the inductors can be reduced. The proposed inductor is applied to a laser-diode driver in a 0.18 mu m CMOS. Compared to conventional shunt-peaking, the proposed circuit achieves 1.6 times faster operation and 60% reduction in power consumption under the condition for the same amount of data transmission and the LD driving current. The interwoven inductor can reduce the circuit area by 26%. Parasitic capacitance in interwoven inductor is discussed. Simulation results reveal that line-to-line capacitance is a significant factor on bandwidth degradation.
