Abstract :
An optical transimpedance receiver front-end that is adaptable to a wide range of bit-rates up to 3 Gb/s has been realized by monolithically integrating high efficiency p-i-n photodiodes with low noise InGaAs junction field effect transistors. The transimpedance-bandwidth product of the receiver is 2.8 THz Omega . The average equivalent input noise current for full circuit bandwidth is 4.0 pA/ square root Hz. The preamplifier for nonreturn to zero data transmission without equalization of the frequency response at 1.55 mu m offers a sensitivity of -41.5 dBm and -29.5 dBm at 140 Mb/s and 2.4 Gb/s, respectively. The dynamic range is 17 dB at 2.4 Gb/s and exceeds 30 dB at 500 Mb/s.<>
