| Abstract: | An integrated laser diode and optical modulator driver for SDH STM-64 lightwave transmitters has been designed and fabricated in a 0.2μm gate-length AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistor(PHEMT)process through CMP of France.The circuit consists of an input matching network,a preamplifier,several source follower pairs,a main amplifier,a capacitively-coupled current amplifier,and an output circuit.Its large-signal bandwidth is over 10 GHz.The eye diagrams were measured at bit rate up to 20 Gb/s with 2.8 Vp-p voltage swing.The driver IC occupies a die area of 1.0mm×0.9mm.Its power consumption is about 1.4W under a single voltage supply of +5 V. |
