10-13.6 Gbit/s 0.18 /spl mu/m CMOS modulator drivers with 8 V/sub PP/ differential output swing

摘要

A novel intrinsic drain-gate capacitance (C/sub DG/) feedback network is incorporated into the conventional cascode circuit configuration to implement a 10-13.6 Gbit/s modulator driver. The driver fabricated in 0.18 /spl mu/m CMOS process could generate an 8 V/sub PP/ differential output swing. The power consumption is as low as 0.6 W. The present work shows that the driving capability is greater than the currently reported CMOS drivers.
