Abstract :
Heterojunction bipolar transistors (HBTs) in the InP/InGaAs material system have been integrated, for the first time, into a transimpedance preamplifier circuit suitable for long wavelength photoreceivers. The preamplifier was also integrated with an InP/InGaAs p-i-n photodetector to realize a monolithic optical receiver. Both circuits had a bandwidth of 500 MHz and operated at 1 Gb/s with an optical sensitivity of -25.5 dBm for the preamplifier connected to an external photodetector and -26.1 dBm for the monolithic photoreceiver. The results demonstrate that there is no compromise in performance as a result of the monolithic integration.<>
