Abstract :
A 3.6 kΩ InP HBT transimpedance amplifier (TIA) has been demonstrated with a bandwidth of 60 GHz. Gain flatness of ±2 dB and DC power of 271 mW has also been obtained. This TIA benchmarks the best gain-bandwidth product (GBP) of 1.9 THz, the highest transimpedance-bandwidth product (TZ-BWP) of 216 Ω-THz, and the highest TZ-BWP per DC power efficiency of +797 Ω-GHz/mW obtained for a 40 Gb/s transimpedance amplifier. These results are discussed in context with prior state-of-the-art 40 Gb/s TIAs implemented with various technologies and circuit topologies. 40 Gb/s photo-receiver requirements, TIA technology and topology trades, and future directions are reviewed.
