A 14-V/sub pp/ 10 Gbit/s E/O modulator driver IC

The development of a high voltage, wideband E/O modulator driver IC is described. The DC coupled, single-ended amplifier exhibits a 3 dB-bandwidth of 11.5 GHz, 9.5 dB small signal gain, and 14-V/sub pp/ output voltage swing. The IC utilizes a 0.25 /spl mu/m pHEMT production process and provides sufficient bandwidth and output power for 10 Gbit/s high voltage E/O modulator applications.
