| 英文摘要 | 研究了光电探测器(Pd)的结构、性能以及后续放大电路,实现了塑料光纤通信的高速单片集成光接收芯片。首先,根据工艺流程和参数,采用器件模拟软件对Pd结构进行了建模,并对其光谱响应度和结电容进行了理论推导及仿真。基于CAdEnCE/SPECTrE软件和仿真得到的Pd参数对由跨阻放大器、限幅放大器和输出缓冲电路组成的后续放大电路进行了协同设计。采用0.5μM bCd(bIPOlAr,CMOS And dMOS)工艺对单个Pd以及Pd和后续放大电路单片集成电路进行了流片、封装和测试。结果表明:Pd的光谱响应曲线的峰值波长和仿真结果较一致,约为700nM,Pd结构更适合短波长探测;Pd的结电容随着反向电压的增大而减小,结电容越大,光接收芯片的带宽越小;对于650nM的入射光,在小于10-9的误码率条件下,光接收机的灵敏度为-14dbM;最后得到了150Mb/S速率的清晰眼图。实验结果显示,设计的高速单片集成光接收机可以应用于百兆速率光纤入户通信系统。; The structure and characteristics of a photodetector(PD)and its post amplifiers were investigated,and a high-speed monolithic optical receiver for Plastic Optical Fiber(Pof)communication was implemented.Firstly,a model of PD structure was established and simulated in a software simulating device based on the process flows and parameters.The spectral responsibility and ajunction capacitor were also derived in theory and simulation.Then,the post amplifiers consist of a trans-impedance,a limiting amplifier and an out buffer were simulated in Cadence/spectre by using the PD parameters.Finally,by using the 0.5μm(Bipolar,CMOS and DMOS)BCD process,the single PD and the monolithic integrated circuit of PD and post amplifiers were taped out,packaged and tested.The tested results indicate that the peak of optical spectral responsible curve agrees with that of the simulated curve,and the wavelength is about 700nm.The junction capacitance of PD decreaseswith increasing of the bias voltage and the bigger the junction capacitance,the smaller the bandwidth of optical receiver.For a 650nm input light,the sensitivity of the optical receiver is-14dBm under the bit-error-rate of 10-9.Moreover,a clear eye-diagram with the speed of 150Mb/s is achieved.The designed optical receiver can be applied to 100Mb/s optical fiber communication systems.; 国家自然科学基金资助项目(No.61205060); 福建省自然科学基金资助项目(No.2011J01361); 福建省科技计划重点项目(No.2013H0047) |
