【 摘 要 】

References(5)Cited-By(2)In this paper, a low power 24mW 5Gb/s differential output transimpedance amplifier (TIA) is realized in 0.18µm CMOS technology for optical interconnect application. The TIA is a fully balanced and differential architecture design that can improve immunity with the common mode noise attributed to the power supply. The differential gain achieved is 66dBΩ with a -3dB bandwidth of 4.0GHz for a 0.5pF photodiode capacitance (Cpd) by implementing both the active inductor peaking and capacitive degeneration techniques. The TIA core consumes only 24mW power from a single 1.8V power supply while achieving the sensitivity of -19.0dBm for a bit error rate (BER) of 10-12.
