Abstract

We report the circuit design of first 25G burst mode TIA in the world, fabricated by 0.13 μm SiGe:C BiCMOS (ft/fmax =300/500 GHz), and the evaluation results when used 25G-PIN- PD. We confirm excellent receiver sensitivities at BER=10-2 are - 20.2 dBm(OMA) for 25.78-Gbit/s and -23.2 dBm(ave) for 10.31Gbit/s, respectively. When we calculate equivalent performances when assumed 25G Ge/Si APD, these receiver sensitivities at BER=10-2 are equivalent to -29.7 dBm(OMA) for 25.78-Gbit/s and -32.3 dBm(ave) for 10.31-Gbit/s, respectively. The burst dynamic range (loud/soft ratio) to satisfy a post-FEC error condition is greater than 25 dB. We confirm excellent TIA performances that will enable a high power class OLT receiver in 50G-EPON in IEEE802.ca.
25.78 gbit /s突发模式TIA,用于50G-EPON OLT
本文报道了世界上第一个采用0.13 μm SiGe:C BiCMOS (ft/fmax =300/500 GHz)制作的25G突发模式TIA电路设计,以及使用25G- pin - PD时的评估结果。我们证实,在BER=10-2时,出色的接收器灵敏度分别为- 20.2 dBm(OMA)和-23.2 dBm(ave),分别为25.78 gbit /s和10.31Gbit/s。当我们计算假设25G Ge/Si APD时的等效性能时,这些接收器在BER=10-2时的灵敏度分别相当于-29.7 dBm(OMA)和-32.3 dBm(ave),分别为25.78 gbit /s和10.31 gbit /s。满足后fec误差条件的突发动态范围(响亮/柔和比)大于25 dB。我们确认了出色的TIA性能,将在IEEE802.ca的50G-EPON中实现高功率级OLT接收器。
