| 摘 要： | A zero-pole cancellation transimpedance amplifier（TIA）has been realized in 0.35μm RF CMOS technology for Gigabit Ethernet applications.The TIA exploits a zero-pole cancellation configuration to isolate the input parasitic capacitance including photodiode capacitance from bandwidth deterioration.Simulation results show that the proposed TIA has a bandwidth of 1.9 GHz and a transimpedance gain of 65 dB·Ωfor 1.5 pF photodiode capaci- tance,with a gain-bandwidth product of 3.4 THz·Ω.Even with 2 pF photodiode capacitance,the bandwidth exhibits a decline of only 300 MHz,confirming the mechanism of the zero-pole cancellation configuration.The input resis- tance is 50Ω,and the average input noise current spectral density is 9.7 pA/√ Hz.Testing results shows that the eye diagram at 1 Gb/s is wide open.The chip dissipates 17 mW under a single 3.3 V supply.
