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

Fully differential, 40 Gb/s regulated cascode transimpedance amplifier in 0.13 µm SiGe BiCMOS technology

“…The TIA measurements confirm that the RGC configuration used in this design, help to obtain reasonable performance comparing to published work. A summary of the performance of the present TIA and previously published works is shown in TABLE 1. Comparing the performance of the presented TIA with the common base TIA reported in [5] shows that for similar bandwidth the proposed TIA has twice as much gain and half the power dissipation. An attractive configuration for very high-speed applications is the distributed method.…”
