A transimpedance amplifier for OC-768 applications designed using a SiGe HBT BiCMOS technology

Abstract
TIA's were designed with transimpedance gains of 230 /spl Omega/ and 240 /spl Omega/, with corresponding bandwidths of 30 GHz and 29 GHz, respectively. Because the simulated results in the 50 /spl Omega/ test environment match reasonably well with the measured results, it is expected that the TIA performance, when packaged with an appropriate photodiode, will improve, as the simulated results for a TIA with a photodiode indicate.
