Abstract
We have developed a high-output-voltage monolithically integrated driver circuit for an external optical modulator using InGaP/GaAs HBTs with a collector breakdown voltage, BVceo, of 14 V. The driver circuit consists of an input buffer stage, two differential gain stages, an emitter-follower prefinal stage, and a final differential stage. The circuit operates stably with output signal voltage of 5.5 V at up to 12 Gb/s with a single-phase ECL-level input signal. Error-free operation is confirmed from the NRZ 2/sup 23/-1 PN pattern obtained at 10 Gb/s.
