Abstract :
Two integrated circuits, a modulator driver and a photoreceiver integrating a metal-semiconductor-metal (MSM) photodetector, a differential transimpedance amplifier and two limiting amplifier stages for high-speed optical-fiber links are presented. The IC´s were manufactured in a 0.2 μm gate-length AlGaAs-GaAs high-electron mobility transistor (HEMT) technology with a fT of 60 GHz. The modulator driver IC operates up to 25 Gb/s with an output voltage swing of 3.3 Vp-p at each output. The 1.3-1.55 μm wavelength monolithically integrated photoreceiver optoelectronic integrated circuit (OEIC) has a bandwidth of 17 GHz with a high transimpedance gain of 12 kΩ. Eye diagrams are demonstrated at 20 Gb/s with an output voltage of 1 Vp.p
